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.

By Species

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.

The bees' first victim.

Toothy got zero allergies because these might be wasps or the writers are inconsistent.

Butterflies and Moths

A butterfly was killed by carnivorous plant in Idol 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.

So a moth can survive being stuffed in a pocket but a bird can't?

How beautiful.

Not even the most brutal of soldiers can resist the fragile nature of a butterfly.

Poor thing.

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

The Demon

Main article: The Demon

The demon is a monster from hell that posseses Cub and kills Petunia in Read 'em and Weep. Since it's a demon, one would expect the creature to have a more ghostly or devil-like appearance, instead it looks more like a cephalopod.

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.

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 swimming 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.

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

These maggots have all of the sugar they could ever eat.

Spiders

Spiders have made several appearances 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.

Maybe Lumpy is an idiot because a spider keeps sucking the blood from his brain.

There's a spider in the water hole!

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.
