- Main article: Truffles
One of the characters fans had to vote for in Vote or Die, he ultimately lost to Lammy and Mr. Pickels. However, he had made a very short cameo appearance in A Bit of a Pickle. He has also appeared in some other episodes afterwards.
- Main article: Generic Tree Friends
Used in masses when needed, for example, in a large audience. They are also occasionally killed as a whole group. Some of them look like a darker version of Toothy without a tail, though they resemble a variety of animals in some of the earlier episodes.
- Main article: Giggles' Mother
Giggles' Mother appears for the first time in the episode Helping Helps. After she thought Giggles was killed by a tidal wave, she was just horrified, but she was quickly cheered up when Splendid delivered Giggles to her (but she had no idea that Giggles was dead or had an acorn for a head). She is one of the few characters who is as tall as Lumpy. She is voiced by Dana Belben. Another episode with Giggles' Mother in it is currently being worked on, but it is unknown when or if it will air.
- Main article: Prehistoric Sniffles
This prehistoric anteater appears in the episode Blast from the Past. This anteater is the ancestor of Sniffles and, at the time, was friends with the Ants. However, when he saw Sniffles eat one of the Ants, he ate one too and liked it, therefore starting the feud between ants and anteaters. Like the modern Sniffles, he also carries a pen protector. He is voiced by Liz Stuart.

- Main article: Fall Out Boy
The band members appeared in the music video for The Carpal Tunnel of Love. They are depicted as Happy Tree Friends bears, and they are also killed together in the same style as Happy Tree Friends.
- Main article: Pod Lumpys
When a small green alien seed fell from outer space and landed in Lumpy's bag of seeds, Lumpy found it and planted it in his garden. It then grew into a giant pod that brought the first green Lumpy clone to life. It could be that when Lumpy touched the alien seed, it absorbed some of his DNA and took on his form. Every time Lumpy chops off any part of a clone's body, it regenerates into more clones, which is based on the enchanted broomsticks from the famous segment of Fantasia, "Sorcerer's Apprentice". They killed Cuddles, Petunia, and Sniffles. Lumpy tried to poison his clones to death, but it turns out that they are totally immune to any Earth toxin, so, at the end of Peas in a Pod, he got them to perform different tasks, such as delivering papers and acting as Lumpy's mode of transportation complete with a car alarm. Some of them died or got injured, while the rest of the clones are still alive.
- Main article: The Interviewer
- Main article: Buddhist Monkey
A special character that starred in his own special episodes. The first episode was Books of Fury, and he was featured a second time in Enter the Garden. If you watch closely on Blind Date, the movie being played is Books of Fury, in Rink Hijinks there was a picture of him on a crane machine, and in Keepin' it Reel he was on a movie screen once again. He is the only star-character that hasn't died. Buddhist Monkey has undertaken more adventures in the spin-off Happy Tree Friends Action series: Ka-Pow!.
- Main article: Panda Mom and Panda Baby
She and her child first appeared in the episode Books of Fury. There Panda Mom was on a library ladder fixing up the book shelves and was almost caught in the fight between Buddhist Monkey and a Generic Tree Ninja racing down the aisle. However, when Buddhist Monkey avoided killing her, it shows how compassionate he is towards other good characters. Panda Mom also appeared in Three Courses of Death. In that episode she was rummaging through garbage for food, indicating she is poor. During the episode, she observed Buddhist Monkey's fight. After the fight, The Giant Crab's claw floated and was beached next to her, in which she promptly celebrated due to her new supply of food.
- Main article: Pig Child
The final character to appear in Mole in the City. This child was present when the Elephant Balloon Vendor was killed by the falling glass. He was devastated by the Vendor's Death until The Mole gave him his balloons, which lifted the child away. It can be assumed he died when the balloons popped and he fell back to Earth.
- Main article: FatKat
The sports cat first appeared in Take Your Seat. He was sitting behind Flaky. He was based off the mascot of FatKat (the company who animated the HTF TV Series).
- Main article: Elephant Balloon Vendor
The Elephant Vendor appeared in Mole in the City. He was killed by falling glass when The Mole jumped through a window. After he was carved up, he released his balloons, allowing The Mole a safe landing.
Genies are mythical, wish-granting beings. Lumpy and Giggles are genies in As You Wish. They both wore vests and fez caps and both of their lamps were located in Petunia's lamp shop at the start and end of the episode. Lumpy's lamp was blue and Giggles' lamp was pink. Petunia threw out Lumpy's lamp because it didn't work. Lumpy granted one wish to everyone who rubbed his lamp, but the wishes always backfired and caused the death of the wisher and others. The wish killing the characters was sometimes caused by bad luck (e.g. Sniffles) and sometimes caused by Lumpy's stupidity (e.g. Cub). It is is not known if Giggles' wishes bring death to her wishers, but, as she is smarter than Lumpy, it can be assumed that they don't. Lifty and Shifty chase after the lamp in order to get their wish (money), but their wish causes them to die as well. In the end, Giggles appeared to Lumpy, ready to grant him a wish. Characters that made wishes are:
- Nutty: A scrumptious lollipop - chokes to death on it.
- Disco Bear: A giant disco ball - the sun's rays reflected off the glass of the ball and burned him to death.
- Pop: That Cub's toy firetruck was fixed - Cub catches on fire and is run over by a real firetruck (this was the only wish that didn't cause death to the wisher, but rather killed his son).
- Sniffles: A spaceship (even though, technically, he wished for "a big rocket") that fell on and crushed him. Then it activated, killed Mime and Pop, and wounded Petunia.
- Lifty & Shifty: A safe landing (which, unless Lumpy could read their thoughts and/or was aware of their predicament, probably granted as a freebie) and money - The balloon in the hot air balloon they were flying in turned into a giant money bag, which made it fall down, killing the brothers and injuring Petunia.
- Lumpy: Unknown, as the episode ended before he made his wish (Although a popular theory among fans is that it probably was sex.).
- This is an article on Lumpy as he appears in Dunce Upon a Time. For information about the character, see: Lumpy.
Giant Lumpy is Lumpy as he is seen in Dunce Upon a Time. He lives in a castle in the sky and is similar to the giant in Jack and the Beanstalk. He is portrayed as a villain, eating the normal sized characters and brutally killing them when they escape. He also keeps Petunia as a slave princess to spin straw into gold for him. When Giggles sees Lumpy killing some of the other characters, she tries to save them. Unfortunately, they end up dying in even worse ways than they would have if they had remained in their jars. Giggles kills giant Lumpy by cutting down the beanstalk while he was climbing down it. He fell to his death, where he lay like a bridge across a valley. A piece of his castle then comes down and crushes him in half, as well as killing Lifty & Shifty.
- Main article: Sneaky
Sneaky is a chameleon and one of the commandos who is on Flippy's side. He has the ability to blend into his surroundings and is able to stretch his tongue long enough to grab enemies or items.
- Main article: Mouse Ka-Boom
Mouse Ka-Boom is a mouse who is also on Flippy's side. He specializes in explosives and his ears appear to be wrapped in bandages due to hearing loss caused by series of explosions. He is French as evidenced by his appearance and the fact he usually says "Le (something)."
- Main article: Sensei Orangutan
The Orangutan Master is an elderly martial artist sensei of Buddhist Monkey. He once showed his apprentice how to create fire with his fingers. His tombstone is seen at the end of Three Courses of Death and how his spirit visited Buddhist Monkey in a fight with Char Sui and the Giant Crab proves that he is dead.
