In the early Internet shorts, his teeth simply became crooked. In later episodes when he flips-out he blinks changing his pupils from normal pac-man pupils to round pupils, his irises turn yellow, his voice deepens into an angry growl, and his teeth get sharp. If he is in his evil state, he (along with Lumpy, The Mole and Cro-Marmot) doesn't have Pac-Man shaped pupils.Īlthough Flippy can be the most cruel and dangerous character in Happy Tree Friends, his good side is considered to be one of the most sociable and kindest of characters. This is proven in several episodes where he is seen doing social activities with some of the other characters such as going to the movies and playing hide and seek.

In most of the episodes where he appears, he is shown as a friendly and social before he goes crazy, or as many people say, "flipping-out" (thus his name). Also, you can see that when he "flips-out", he does not remember the bloody rampage that follows. However, in Double Whammy Part 1, (and possibly starting from Hear Today, Gone Tomorrow when he resists his evil side for the first time) he finally realizes his problem and goes to Lumpy the psychiatrist for answers. After three atempts to cure him, Lumpy fails. At the end of Double Whammy part 2 Flippy finally cures his post tramatic stress disorder but is killed soon after by a chicken truck. He is usually killed by explosions or machinery. He also has an allergic reaction to peanuts (or venison) just like Flaky, but he doesn't puff up like her.
