The Baboon is a non-anthropomorphic character in Happy Tree Friends.
It appeared in From A to Zoo as one of the animals in the zoo that the characters visited. Cuddles and Toothy tormented it by poking it with a stick prior to Sniffles asking Lumpy to take a photo of him with the baboon. The humiliation he suffered in addition to being locked in a cage and the camera's sudden bright flash enraged the baboon, whereupon it tore Sniffles to pieces. It somehow escaped the cage and wandered around the zoo with Sniffles' camera, trying to configure it. During his wander, he spotted Cuddles. Thirsty for revenge, the baboon made his way to Cuddles, frightening him and indirectly killing him when Cuddle's eye is inflated to a balloon by a nearby helium tank. It managed to get onto the bus, wearing Sniffles' glasses to trick Lumpy. As the episode ended, the baboon took a photo of himself. The flash caused it to go crazy again, leading Lumpy to crash the bus, possibly killing Lumpy, Flaky, and the baboon itself. The baboon seemed to have some intelligence, as it could remember Cuddles and hold a grudge against him, as well as trick Lumpy into thinking he was Sniffles (because of the camera and his glasses).
- Sniffles - 1 (From A to Zoo)
- Cuddles - 1 (From A to Zoo) (Indirect)
- Lumpy - 1 (From A to Zoo (Debatable))
- Flaky - 1 (From A to Zoo (Debatable))
Note: If the Baboon did kill Lumpy and Flaky, it could have directly (attacking them) or indirectly (from the resulting crash). If they survived the crash, the Baboon probably killed them afterward.
- From A to Zoo: Possibly died when the bus crashed (Debatable).
