Ogthar's plastic surgery to make himself look like a human
Ogthar is a member of The Barney Bunch. He's a human/triceratops hybrid that was found in The World Beneath in the Dinotopia books. He also once got plastic surgery in 2005 in Dinotopia:Quest for the Ruby Sunstone to make him look human, but this really pissed off Hewy Toonmore so he changed back his looks. He also has a bunch of dino studders (even though in the animated movie mentioned above that they were made to do evil things, but in the books they weren't).
