Despite its childish appearance and cute name, the show is extremely violent, with almost every episode featuring blood, pain, and gruesome deaths.
As indicated on the official site, it is "not recommended for children under 12". The portrayal of death in Happy Tree Friends is usually graphic and exaggerated, depicting bloodshed and dismemberment in a vivid manner. The episodes last from between 1 to 7 minutes.
Happy Tree Friends is an American Flash cartoon created and developed by Aubrey Ankrum, Rhode Montijo, Kenn Navarro and Warren Graff. The show has become a popular Internet phenomenon.
All the characters are anthropomorphic mammals, and all of them (except Lumpy, Buddhist Monkey, Evil Flippy and Sniffles) have two front buckteeth and pink heart-shaped noses. In early episodes, most characters played the roles of children doing childish games. However, as the series progressed the age concept was dropped, and now characters act variously like children, teenagers and adults in different episodes. The only characters who are unaffected by this concept are Pop and Cub, who always act like an adult and a child respectively, and characters whose roles usually are not affected by age, such as Splendid or Cro-Marmot.
