I’m fairly sure that it is the same Baby Groot hug Metallica Guitar shirt entity and not offspring. Rocket didn’t find a seed or anything that would suggest offspring, he found a limb that he figured would regrow. Which it did. So I’d say it’s safe to say that this baby Groot is still Groot. Just that since he’s so very tiny I’m guessing it causes him to revert a certain amount until he can regrow back to his former glory. Simple answer, buy a Spiderman figure and a Dancing Groot toy. Place within reach of small children. Be prepared to buy lots of batteries and earplugs. Baby Groot – which I assume refers to the character from GotG Vol. 2
because Groot is more of a teenager Baby Groot hug Metallica Guitar shirt in Infinity War – says three words: I, Am, and Groot. Always in that order. He may be the only (last?) of his species, and he’s regarded as “too adorable to kill” by Taserface, but he doesn’t appear to have abilities that are unusual for a tree. He also dances. Baby Yoda – technically named The Child – says nothing. He is definitively not the last of his species, and is highly Force-sensitive, utilizing it to briefly levitate a mudhorn, choke a perceived enemy, and heal poisonous wounds. He also doesn’t dance.
