As a fun challenge, I made a creature with the help of some prompts. These prompts were then randomly selected and used as a base to create this guy.
1st animal: Cheetah
2nd animal: False Killer Whale
1st texture: Hedgehog spikes
2nd texture: Sharp feathers
Special feature: Octopus' color/texture change

I ended up combining the spines and the octopus like texture change. It has spongy bobly bits on its skin that harden into spikes when tense. And the sharp feathers got changed into quills cause I want this to be more of a mammal.
