Monsters

Monsters are creatures which attack the Happy Tree Friends. They arn't animals or normal characters. Most of them have killed at least one another character and all of them have injured a character. Monsters include creatures, spirits, plants and aliens. Sometimes they are different version of one of the main characters (mostly Lumpy). They mostly appear in Halloween specials.

Dinosaurs
The dinosaurs appear in Dino-Sore Days. One of them attacks Cro-Marmot when he thinks it was a dead dinosaur he saw nearby. It bites his head. He escapes it by swinging away on its guts which he uses like a lasso, only to be caught and devoured by a pherodactyl which was unfortunally flying nearby. She then feeds Cro-Marmots remains to her babies. The pherodactyls arn't actually dinosaurs, and they are resonsible for one of the only official deaths of Cro-Marmot.

Zombies
Seen in Remains to be Seen, they are the dead bodies of the trick & treaters that flipped-out Flippy ran over (and Flippy). They most likely rose from the dead because of the nuclear waste in the back off Flippys truck. They rose from their graves and attacked Lumpy. Zombie Flippy mainaged to bite Lumpys arm off. Lumpy used a leaf blower to make Flippys brain swell up. When zombie-Toothy bit the brain, the brain exploded, killing all the zombies (exept The Mole) and burrying them again. After the zombies were all dead and Lumpy thought it was all over his severed hand attacks him, but he mannages to pull it off. Characters that got zombiefied are Flippy, Cuddles, Giggles, Toothy, Sniffles, The Mole, Handy, Petunia, Lifty and Shifty, Russell, Mime, Nutty and several Generic Tree Friends. Lumpy was partially zombified as only his hand became zombiefied.

Genies
Genies are mythical wish-granting beings.
