Here are 15 Things You Didn't Know About Baby Groot.

15. He Was Not Originally Supposed to Be in the Movie

Can you imagine a world without Baby Groot? Us either, it's just not a place we want to live in. But terrifyingly, we all almost had to endure a Baby Groot-less existence. When director James Gunn was writing the sequel, he planned on it taking place several years after the first, with a fully grown Groot back in action. Fortunately for the rest us, something just didn't seem right:

First of all, I thought there was a lot of development the group needed to go through as a group – and it would be a shame for the audience to miss it. And, secondly, for whatever reason, Groot just wasn’t working. It was then I came upon the idea of having Vol. 2 take place very shortly after the first film and for Groot to still be Baby Groot, with quite a lot to learn.

So Gunn altered the timeframe of the film and the rest is Baby Groot history...

This change opened up the whole movie for me and it suddenly all came together. I fell in love with the script for Vol. 2, and I felt like we were creating something very special.

And that something special was an adorably tiny tree who occasionally wears miniaturized space-pirate outfits. So for all those who thought Baby Groot was nothing more than a clever marketing ploy to sell toys, t-shirts and Mr. Potato Heads, shame on you. Baby Groot would never sell-out.

14. A Life-Size Model of Baby Groot Was Built for Filming

Few have the commanding on-set presence of Baby Groot. Quite the achievement for someone who is only 10 inches tall. Even more impressive? Like Bradley Cooper and Vin Diesel, he never actually showed up for work. That's because all his scenes were created in post with CGI and special camera rigs that captured his perspective during shooting. But that doesn't mean his fellow actors were talking to an invisible tiny tree on-set.

With both Dave Bautista and Chris Pratt towering above Baby Groot at over six feet apiece, the filmmakers had a particularly challenging time framing out their Groot-centric shots. To make things easier, prop master Russell Bobbitt sculpted a 1:1 scale model of Baby Groot to use for filming. He would even occasionally puppeteer the model to give the actors someone to interact with, which just seems like the best job ever. “Hey Rus, what'd you do today at work?” “Oh not much, just pretended to be Baby Groot all day.”

13. His Look is Based on Real-Life Human Kids

There is no denying when you look at Baby Groot that he's an adorable, cute baby. Puffy cheeks, toddler pot-belly, stocky limbs, oversized head -- all the signs are there, only petrified. These anthropomorphized characteristics are probably one of the reasons we find him so endearing. Because who wouldn't want to be the proud parent of Baby Groot? Amazingly, enough that one person can actually make that claim.

To get just the right feel for Baby Groot's look, concept artist Anthony Francisco drew upon his own children for help. As he shared on Facebook:

'GOTG Vol.2' was all about family and this character is so close to my heart because my kids were the inspiration that helped me in finding the design. And my son is much like baby groot, he is a handful but always cute and adorable.

How cool is that for Anthony Francisco's kids -- that they can stroll the sand box confidently proclaiming “I am Baby Groot.”

12. He Has His Own Special Script

If there's one thing the galaxy should know by now, it's not to underestimate a Baby Groot. Take his vocabulistics, for example. If you thought this sentient sapling only knew three words, think again. Turns out that there is a whole world of meaning to read between the lines of each and every “I am Groot.”

To help Vin Diesel capture just the right inflection for each of Baby Groot's scenes, James Gunn wrote a “Groot Version” of the script just for the two of them. In it, every one of Baby Groot's lines is translated into English to show exactly what the little guy was saying, such as when he gleefully ran off with Rocket's death button. All and all, he utters his famous line 17 times during the film, which leaves a lot of room for interpretation. But really, what more is there to say? As far as we're concerned, “I am Groot” suits every occasion just fine.

11. Baby Groot Speaks Sixteen Languages

Vin Diesel famously recorded the voice of Groot 1,000 times in six different languages for the first film (then added another 9 when it was released on DVD). For the Guardians' second go around, Diesel upped his vocabulistics game by saying “I am Groot” in sixteen foreign-languages.

Despite the added work, Diesel was all for it:

It means that my voice is being heard in countries where that’s not always the case… It’s usually voice actors in respective markets that say your lines and that’s not necessarily what the character is always. So, I love that, but it definitely makes it that much more challenging.

It's a good thing too. Because personally, we don't think anyone else could capture the fine nuances of Baby Groot's voice any better then Dominic Toretto.

10. Baby Groot's Voice is the Unedited Baby Talk of Vin Diesel

When we think adorable baby voices, naturally we think of Vin Diesel. That's why it only made sense that the Fast and the Furious star would reprise his role from the film as Groot. But while Diesel’s distinctive mumble growls and deep-tone lent itself well to the wooden vocalizations of adult Groot, you wouldn't think they would have the same fit for a tree baby. But apparently, there's a much softer side to Vin's voice than we ever realized.

Leading up to the release of Guardians of the Galaxy Vol. 2, Diesel would reprise his role, only without his trademark gruffy intonation. Even more mind-boggling was the fact Gunn later went on record as saying that they did very little tweaking to Vin's vocal performance in post-production, meaning what you hear on screen is almost 100% the childlike voice of a 49-year old grown man. Apparently, on top of driving really fast and fighting aliens in the dark, Vin can also do a spot-on baby talk, high- and all. Who knew? Anyone that's ever heard the man do karaoke, that's who.

9. James Gunn Did the Baby Groot Dance (Again)

Vin Diesel may be the voice of Groot, but James Gunn has got his moves. It is well known by now that when Groot got down to the sounds of The Jackson 5's I Want You Back during the credits of 2014's Guardians of the Galaxy, it was actually James Gunn waving those arms around. The Motown boogie was animated using footage he had captured while dancing privately to the song. In case you don't believe it, Gunn has since given us a glimpse of his skills.

Given the global sensation having Groot bust-a-move caused, it was a given that he would return to form for the sequel. But whereas we got just a tease of a grooving Groot the first time around, Guardians of the Galaxy Vol. 2 wasted no time in opening with an epic routine to rock our socks off, all to the tune of Electric Light Orchestra's Mr. Blue Sky. And once again, we have James Gunn to thank for making our dreams come true, as he served as the motion-capture model for Groot's hip action. Even though the routine was similarly choreographed behind close doors, Gunn has snippets) of his performance. However, far more went into Groot's adorable dance than just one-man dancing alone in a room. In fact, the CG rendering of this one scene took the visual effects team nearly two years to complete.

8. He Has No Memories of His Old Self

One of Groot's many, many awesome superpowers, along with killing space clowns and flying through space, is that he can regenerate himself from the smallest shards of his trunk. A mere potted branch will do the trick, as we saw at the end of the first film. Which is great news, because it basically means he's basically immortal and won't be leaving us anytime soon. But as fate would have it, Groot loses a lot more than his size when he regrows back to life.

When asked how Baby Groot compares to his adult-sized counterpart, James Gunn stated that he has lost all memory of his previous self, and for all intents and purposes, he is now an entirely different creature. Which is incredibly sad when you think about it, because that means the original Groot did actually die at the end of the first film. This differs greatly from the comics, where each time he gets blown to bits, Groot is reborn with all of his original memories, mannerisms, and abilities, as if nothing had happened at all. Though, you can kind of see why Gunn went his route, since in today's day and age of characters haphazardly dying only for it be reversed s later, it makes this petrified superhero's sacrifice all the more meaningful.

7. He Was a Dancing Ambassador for Earth Day

Nothing says conservation more than dancing like a baby tree. Which is why making our sentient stomp-hopping friend the good-will floral ambassador of Earth Day is such a good fit. Prior to the release of Guardians of the Galaxy Vol. 2, Marvel teamed up with the Disney Conservation Fund and Nature Conservancy to make the world a better, greener, more Grootier place. And also get a lot of people dancing.

The promotion, co-led by dancer D-Trix and the tiny hero himself, asked fans to move like Baby Groot behind people without their knowing and then post videos of it using Marvel made a $1 donation to plant a tree. When all was said and done, 250,000 new trees were kicking it across the planet. Suck on that, Drax.

6. You Can Make Your Own Baby Groot

No, we're not talking about having sex with a tree. That would be gross and disturbing, and probably land you in jail. This, on the other hand, will make you the envy of all your friends. That's because there are plenty of socially acceptable ways to create your very own Baby Groot.

Over on the blog Twinkie Chan!, there's a thorough instructions on how to turn his head into a flower pot. And for anyone whose had a strong desire to eat Baby Groot, you can bake a Baby Groot cake. Or you could just save your self a crap load of time and buy a Baby Groot. There's only about a gazillion trintillian different Baby Groot-related products out there to choose from.
