Alvin (full name Albanese) is well a gummy gator with a white marshmallow underside, blue razzberry body, legs, tail, and left arm, off white pineapple right arm and head. (had to pick 2 of my fav flavors of course) He wears a light blue captains styled hat. He has this light blue gemstone looking thing where a belly button would be. That gem is quite literally where the magic happens~

Being what he is he's naturally soft and squishy, but the magic gem imbedded in him lets him do so much more!
Alvin has the gem in him because when found it he ate it whole without thinking assuming that he found an absolutely delicious looking huge piece of rock candy. The gem is permanently attached to him, no matter how hard he tried it never came off. But his newly obtained bling has come with plenty of up sides that made it worth doing in the first place. (he has since learned to think before he acts more after this, sometimes)

The gem allows him to freely shapeshift and alter his body. He can stretch his body (either by making himself longer like elastic or outward (say with being filled with air), reshape his body (like turning himself into a ball or turning his hand into a hammer), make himself or parts of him bigger, as well as make himself flat on command (he can be crushed/smushed by things too). He can also alter his structure making himself all melty and goopy or harden himself. (being made of candy he is only so hard when he does this) He can also be cut and/or be torn into pieces and be just fine. (he is technically edible much his actual horror) The gem also sustains himself, so he doesn't need to eat or sleep anymore. (he still can do those it's just optional for him) His body can regenerate if parts of him are destroyed (or eaten), the regeneration isn't instant but is fairly quick.

He’s a doofus (he’s not a complete idiot but he’s not the smartest guy either) who’s down to clown and try all sorts of things even it seems weird to most others. He is a boat enthusiast, it’s why he wears the hat has. He’s very open minded about everything and every kind of person and doesn’t judge people for anything really, mostly. He has a habit of not thinking things through hence why he now has his gem and shapeshifting abilities, simply put he has a hasty nature.

Some miscellaneous things about him.
Age 22, height 5'8" (172.72 cm), and his favorite kind of boats are sailboats.
