Flippy
((Voiced by Aubrey Ankrum (2000–) and Kenn Navarro *Good Flippy* (2000–) )) Flippy is a green Male bear with dog tags and a green beret with checkered crest. There is evidence to suggest that he fought in the Vietnam War, particularly his obsession with making booby traps inspired by the Viet Cong, as well as a flashback of his experience of being held captive by them (as seen in Easy for You to Sleigh). In addition, his attire seems to resemble to the U.S. Army Special Forces, which played a role during the Vietnam War. According to writer Warren Graff, Flippy is mostly based on John Rambo. Flippy rarely appears in the series, most likely due to his repetitive behavior in most of the episodes in which he appears. He is Happy Tree Friends' most popular character.
Flippy has a severe case of post traumatic stress disorder. Whenever he sees or hears something that reminds him of war (e.g., gunshot-like sounds or crackling campfires), he goes insane and kills everyone around him, believing that he is still in war. While insane, several physical features about him change: his eyes turn a different color, usually green or yellow, his voice changes from high and cute to low and evil, and his teeth become sharp. In the early Internet shorts, his teeth became crooked.
Although 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 should many people say "flipping-out." Also, after he "flips-out", he does not remember the bloody rampage that follows. However, in Double Whammy, (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. He then removes his 'evil' side on Double Whammy Part 2/ Autopsy Turvy, but is soon killed by a chicken truck.
So far, Flippy has killed every character, with the exception of Splendid. (His bomb depicted on the Overkill DVD Box Set may have killed Splendid, but it is still debatable.) His own confirmed deaths (killed twice in Remains To Be Seen) were all caused by machinery. Most of his deaths were caused by some kind of vehicle, whether he was operating it, or another character was. Along with that he is also killed in explosions.
He'll star in an upcoming episode with Splendid in a while.
