These are goofs that appear in the TV series of Happy Tree Friends.
Note: Do NOT add images that depict a character doing something stupid, as many characters do idiotic stuff. Only add in animation errors or an impossibility in logic.
Russell is missing his whiskers, and if the show was following real logic, Cuddles and Russell's hats would fall off, as it is soon revealed that they are upside-down.
The sign has no construction hat on it...
...but now it does.
Lifty is notably bigger than Shifty when they are often equally sized.
Lifty's jaw dislocated from his face.
Lumpy's feet are shown getting filed down right here...
...but one of them breaks off, and it is not damaged.
1.The sidewalk goes through the cactus... 2. The cactus was big when Cub went through it, and when Pop is about to go through it...
1. ...but it goes around after Pop goes though it. However, pointing the obvious would ruin the punchline. 2. ...but after he goes through it, it's small.
Cub's eyes are facing each other.
The rope goes through Lifty and Shifty's heads...
...but it's their torsos that get cut in half. Also, Cub can survive with half of his body gone, but not these two?
How could the sea animals damage his eye patch, without breaking his helmet to get to it?
1. Shifty with Pac-Man eyes. 2. Shifty is facing left and his legs are bent...
...now his body is facing right and legs are straight...
...now he's facing to the left with his legs bent once again. Lifty was supposed to let go of the gold Shifty once he died. Also, despite them dying far from each other, Lumpy's corpse is next to them.
Following logic, Shifty's hat should fall off his head.
1. Shifty's ribs should not be part of his skin. 2. Shifty's skin has both arms, despite losing one earlier. 3. Flippy is covered from head to toe in blood...
...so how did he clean himself and get all the way here in a matter of seconds?
The lining around Shifty’s eyes disappear after he blinks in this shot.
A normal person would have died drinking this much mouthwash, and Tree Friends are famously easier to kill than normal people.
Judging by how little the hole on the water heater was...
...the water that spilled out shouldn't pour out that quickly.
I know this is a absolute nightmare to see Petunia looking like this, but it's impossible for the skin on her body to fall in the sink when it's supposed to be on the floor. Skinning her tail off isn't possible as well, as it's made up of fur, and not skin.
Look, I know Lumpy's dead body looks horrifying to look at, but the dead body has no antlers.
Petunia's skin is covered in filth here...
...but after she skins herself, her skin looks clean. Same goes for the potato peeler.
Lumpy is holding the fur from his left hand...
...but is holding it from his right hand in the next shot.
Lumpy is too far away to close the door.
Dirty water can be seen spreading from under the bathroom door...
...but onceLumpy comes over to help Petunia, there's no dirty water puddle near the bathroom door, and the floor itself is completely clean.
Petunia clearly used the towel off the rail...
...which she used it to wrap it around her head...
...and was placed in the hamper...
...but after she flushes the toilet, it's back on the rail in this shot. (And for the rest of the episode)
Petunia's head marking disappears before she hyperventilates over the smudge on her mirror...
...but suddenly reappears when she starts using the paper bag.
...but one seems to appear, when his crushed corpse is shown.
This mud puddle appears...
...then disappears...
...then reappears...
...and then disappears again.
Lifty's mask can be seen splitting into two parts for a frame when he blinks.
In this shot, Lifty's tail can be seen passing through the basket.
Pop can be seen still impaled on the tip of the rocket...
...but once the brothers start falling, Pop mysteriously disappears...
...and once the rocket crashes into the lamp store, the van has somehow disappeared, and Pop's corpse reappears.
Before Lifty and Shifty burst through the ceiling of Petunia's shop, there's a pre-cut/shaded area for the hole Lifty and Shifty crash through. (It's most likely this was done so the animators could tell where to draw the destruction.)
At the beginning of the episode, there is an extra lollipop that can be seen on Nutty's tail.
Sniffles' mouth is supposed to be at the tip of his snout, and not under it. (It stays like this for the rest of the episode)
Nutty's lollipop, sucker, and candy cane are missing when he sucks the honey from the beehive...
...and then the beehive disappears in the shot where he rips off the fur from the bear.
But before he gets sliced to pieces, the candy on him reappears.
The Axe and tent supplies are gone in this shot.
Lumpy's canteen had a strap...
... but now it doesn't.
Isn't this a little dirty for her OCD to handle? But then again, she WAS dehydrated. (However, this episode was written, before the creators decided to give her OCD.)
This Blurb is true...
...but the next one implies otherwise.
Toothy's face is bashed on a rock here...
...but goes back to normal when he is impaled.
Toothy's swollen arm falls off here...
...then somehow reappears when the bear starts to chase them.
Lumpy's nose is clearly drawn shorter than normal.
Toothy trying to pitch a tent...
...then the tent disappears. (However, it's possible that he's doing on the one in the top right in the previous picture.)
Characters briefly shown with Internet Season 2 designs. This might have been intentional, seeing how the animators decided to recycle animation to save money.
When Lifty and Shifty first present the beans to Nutty, there are a blue, yellow, orange, red, magenta, and purple bean...
...but when Nutty presents them to Giggles, the yellow bean becomes a green bean.
Giant Lumpy with no pupils.
1.Considering the length of this hair...
2...and the fact that Giggles tore off Petunia's entire scalp...
1...the hair should have been a lot longer when Giggles hit the ground. 2...Petunia's scalp should be on the end of the hair rope.
...but she is on the left when she reaches the bottom.
Origami cranes cannot flap its wings when its tail is pulled back and forth, it's the origami flapping bird that does that.
Seeing how there's no wall that connects the doors, it would have been easier for Handy to walk around them.
Judging on how off putting this house looks like...
...the tree friends should've realized that something was wrong while they were building the house from the outside. (Though, this could exaggerated and done out of comedic effect.)
Two goofs here: 1. Cuddles looks into the mug, but doesn't notice the coffee inside. 2. Coffee is hot, so how could Cuddles not feel the heat on the cup?
1. A burn like this... 2. Cuddles only splashes coffee on his cheek...
1. ..shouldn't have healed this quickly.
2. ...so why does he also bandage up his ear, which didn't get burned?
How's The Mole playing that trombone when his lips are covered?
No sign of Flippy's helicopter
I know Fliqpy is amazing at killing people, but where is the end of that rope tied to the log?
