The Hydra: the most awesome fantasy-dragon-serpent-creature ever. Why? Because more heads are better, of course. Get this, though - the Hydra has the ability to grow them back-- take that, Cerberus! Okay, okay. It's not a competition, fantasy creatures are ALL great. But to sum up: the Hydra is a writhing pile of serpent heads, fangs and tongues that regenerates. How could it not become a Squishable? That's one amazing fantasy creature!
