Humans



Humans are sentient mammals that don't appear in Happy Tree Friends (anthropomorphic animals take their role). In early episodes, humans seemed to be absolutely nonexistent in the Happy Tree Friends world. However, later episodes showed evidence of human existence.


 * In Sea What I Found, Russell found a treasure chest that was held by a humanoid skeleton. This same skeleton was seen underground in A Hole Lotta Love.


 * In Idol Curiosity, Sniffles exhibits several objects in the museum. Many of these artifacts, like the suit of armor and Moai head, appear to resemble humans.


 * In A Sight for Sore Eyes, there was a poster of what looks like a human eye.

These examples provide evidence that humans do (or at least did) exist in the Happy Tree Friends world. Whether humans ever existed or not in the Happy Tree Friends world is debatable. Perhaps the skeleton and the other evidence was meant to portray other "anthropomorphic" primates, like Buddhist Monkey or Sensei Orangutan. It is unknown if humans will truly appear in in the show (though unlikely). If they do, it is unknown what they would look like in Happy Tree Friends style.
 * In Easy For You to Sleigh, a picture of a possible human head and a suit of armor were seen in Flippy's house.
 * The Cursed Idol looks humanoid in appearance, possibly made from Mesoamericans. Had it and the other objects been made by animals, they would have resembled the HTF style.
