Elasto_Gumdra

Name: Elasto Zip
Species: Living rubber Gumdramon costume
(Inspired by this story)

Elasto is a rather shiny, squeaky digimon, and seems to smell vaguely of rubber. Of course, if you were paying attention to the above, you'd know why. As a living costume, he obviously has a zipper, (It's on his back and runs from the bottom of his neck to the base of his hammer-tail. The zipper is also part of the back of his vest, so he can never truly take it off.) but... don't try and get inside it and then close it; You'll be absorbed into his being... eventually. Of course, the thing has a tendency to get stuck, trapping his occupant inside until the absorption process is over. At least until then, they can feel what it's like to be a gumdramon...
However, this only applies if the zipper is closed all the way. As long as at least an inch (just over 2 and a half cm) of the zipper is left open, it'll still get stuck, but the absorption process won't even start, giving his occupant pretty much as long as they want in there.
Yes, he's life-size, (read: short) But he's also stretchy, so... (Also, he can shrink down his occupants to make it easier to move around.)
His eyes and eyelids are made of a mesh with tiny, close-packed holes, so it's not hard at all to see through them from inside while also making them look realistic besides.
---- His inner cavity looks like pillowy folds of flesh, but it's actually just padding akin to a winter coat.
---- Yeah, it's padding made from previous 'wearers' that he absorbed, but look on the bright side:
---- it's REALLY soft and comfortable, as well as nice and squishy.
He was originally a normal Gumdramon, but after playing a prank on someone he didn't know was one of the Digimon gods, they cursed him to be essentially empty. He's only glad they didn't take away his ability to eat or drink. Btw, they fused the ring on his tail TO the tail, so he can't take it off and Digivolve that way. Just an added penalty.
