Note: All images are put in order.
A group of Happy Tree Friends.
"It's time for trick or treating!"
They're all ready for Halloween.
...a truck filled with radioactive goo rides down the road.
Nothing war-like here. Except his truck... and his outfit.
A lot of radioactive goo.
The group crosses the road.
Everybody's going trick-or-treating.
Something bad is going to happen.
Told you his truck was war-like!
"...it's time to kill someone."
Radioactive goo is very dangerous!
Handy and Petunia's remains.
I know he likes to kill people quickly, but this is cheating.
Now it's the head's turn.
Lumpy's run out of limbs.
Come on, I know you've seen scarier things than that.
Lumpy works as fast as he can.
That'll stop that zombie.
He can't stop those ones though.
Could stop those if you're fast enough.
The zombie Cuddles and Giggles kissing.
"I need to do something!"
Let's hope Lumpy finds something good.
Lifty & Shifty as zombies.
Zombie Russell's killed too.
Zombie Russell's remains.
Lumpy kills more zombies.
"I hope this all is a dream."
"Perfect time to kill you, Lumpy."
Fliqpy's not going down that easily.
"Get ready for some pain!"
Lumpy apparently enjoys the pain.
Watch out! Fliqpy's armed!
Zombie Fliqpy doesn't care very much about the disabled.
Too late to disarm this one, but you can disleg him.
His tail's attached to his back?
The next big thing in zombie fashion.
Goof #5: Lumpy has his left arm back.
Lumpy hiding in the shed.
"Get ready to die, Zombie Fliqpy!"
"Let's turn on this thing!"
Behold! ...A leaf blower!
Zombie Fliqpy is not amused.
Zombie Fliqpy with his eye stuck in a leaf blower.
"Now I need to get this thing of"
"Hmm, well, that worked."
Petunia and Sniffles see a treat, but The Mole blindly wanders behind.
Even the generics want in on it.
"This should be delicious!"
Toothy gets the first bite, causing Fliqpy's death...
...and triggering an explosion.
A crater gets left behind.
A mass grave conveniently created for these undead corpses.
Everything is just fine again.
Lumpy survived the explosion.
Lumpy has nothing to worry about now.
"No! My arm is attacking me!"
Correction: He has nothing to worry about except himself.
He gets his zombie arm off.
Lumpy and his zombie arm.
See the red circle? The Mole is still moving.
