Walking down the street, you see a small Green headed child talking gibberish.
Whenever someone asks this child who they are, it will exclamate loudly "GUMMY!!" before doing a little dance, then run off into a general direction.
Gummy, despite being a normal child, is quite athletic, able to climb most things without much effort
Like most children, Gummy is very sturdy, being able to literrally bounce about after falling from a great height, like most children
Gummy, beyond their name, will exclusively speak in unintelligible gibberish, clearly their mouth can't keep up with their intellect.
