List of Invertebrates

There are many invertebrates that have appeared throughout Happy Tree Friends, and they usually make a very small appearance and a minor one at that. However, some play a pivotal role in the episode in which they appeared in.

The Bees
The bees make their first appearence in Sweet Ride where they kill Nutty when his head gets stuck in a beehive. They appear again in Take a Hike this time showing no hostility to Nutty when he is slurping honey from a hive. In Aw Shucks!, a beehive is knocked off it's branch and some bees swarm around Toothy (though these might be wasps since Toothy didn't get an allergic reaction to their stings). One bee appears in The Carpal Tunnel of Love and it stings Toothy in the eye, causing it to get infected. It comes back later and kills Lumpy when it stings his eye, causing him to crash into the back of a truck.

Butterflies and Moths
A butterfly was killed by carnivorous plant inIdol Curiosity. In Mime to Five a butterfly flies out of Mime's pockets when he's checking to see if he has any money, though considering it's small size it and the fact that it was in a spot where it could eat clothing and pocket lint, it's most likely a moth. Some butterflies are seen flying by in Every Litter Bit Hurts. Flippy might like butterflies because he sees them in his dream in Double Whammy Part I and one butterfly was enough to make Fliqpy snap back to Flippy in By The Seat Of Your Pants.

Clams and Mussels
A clam is eaten by Russell in Russell's season 1 starring pop-up. Russell can be seen eating some of these in Whose Line Is It Anyway?. Russell picks up a clam in Off the Hook with the intention of eating it but he is crushed by an anchor. A lot of clams appear in Sea What I Found

Coral Reefs
A lot corals can be seen in episodes having to do with the ocean such as Off the Hook, Sea of Love, and Sea What I Found.

The Giant Squid
The Giant Squid appeared first in Doggone It. It was a pet until it attacked and killed several characters before being captured by Lumpy. It appears again in You're Kraken Me Up, causing more carnage after Russell accidentally awakens it by dropping an anchor on its head.

The Flies
Flies can be seen flying around the bodies of Cuddles, Toothy, Petunia, and Sniffles in Take a Hike. They are also seen getting splattered against Lumpy's car in Junk in the Trunk.

Jellyfish
A small jellyfish appears in Happy Trails Pt. 2: Jumping the Shark, it stings Giggles' foot and she later dies since no one could treat it. A lot of jellyfish can be seen swiming in groups in Sea What I Found.

The Hermit Crab
This small blue crab appears in Wipe Out!. It is first seen replacing its old shell with an ice cream cone, nearly being stepped on by Lumpy in the process. At the end of the episode, it uses Flaky's severed head as its new shell.

Maggots
They make small appearances in Remains to be Seen, they can be seen crawling on the zombified characters.

The Snail
The Snail was killed by Lumpy in Every Litter Bit Hurts by a toothpick. It also appears in A Sight for Sore Eyes.

Spiders
Spiders have made several appearences in the HTF world. A spider can be seen crawling inside Lumpy's empty water canteen in Take a Hike]. A spider is seen hanging from a web in Nutty's cabinet in [[Chew Said a Mouthful and there's even a spider living in Lumpy's head in Hear Today, Gone Tomorrow.

Starfish
Yellow starfish can be seen in Off the Hook. In Water You Wading For, Cub pokes at a starfish with a stick. A lot of starfish can be seen in Sea What I Found.
