to play Terra Monsters quick!
Tortipous is a turtle platypus thing I designed. The second stage was originally called Tortitaur, but Tortitank is way cooler, I think. This is one of the most popular Water monsters in the game, because, well, he's a tank.
No other tidbits really. He came together in about 1 drawing, possibly 2.
And just cuz I love it so much, here's a link to a sculp of it by a fan! [link]
