Kind of a first attempt to make something 3D-ish and gelatin-y.
This guy's basically a shapeshifter who can make himself goopy, rubbery or rock-hard. He can also do stuff like shloop into grates, bounce really far and stretch out his appendages to grapple stuff from far away. I may have been subconciously inspired by de Blob and Chaos from Sonic Adventure when I came up with this.
