Episode
Well, HTF is more catchy than THTFB.
First HTF Title Card.
And this Lumpy plays the banjo.
Modern Lumpy prefers a cadaver.
How exactly is this guy Lumpy?
The banjo breaks!
Lumpy realizes what's going on...
...and doesn't feel so happy about it.
They never would have to have laughed for Lumpy!
I warned you!
Going from a good dinosaur...
Angry Lumpy Eyes.
...to a Rotten Apple!
An era is about to begin in 3...
...2... 1...
Happy Tree Friends not is more a Children Cartoon!
Lumpy's first kill!
First death in Happy Tree Friends.
One down, three-hundred and sixty-three to go.
"You'll die next!"
OH NOES!
"No! Not my best friend!"
Shouldn't that half be behind Toothy?
They're screwing with logic already.
Is he glued to the log or something?
Toothy watching how he's getting beheaded.
Lumpy still looks unsatisfied even though he already killed everyone.
He needs more blood!
I can guess that Lumpy is going to be a good butcher.
Flying arm.
Not good enough.
Getting there.
Lumpy goes psycho.
That's pretty scary.
Lumpy is preparing a Toothy soup.
Eye see what you did there.
That took brains.
But it really tickled my funny bone.
Did Toothy eat a soup can?
Is he done yet?
Lumpy is now satisfied.
So peaceful.
Toothy is a zombie!
Wait, didn't he lose his eyes?
Toothy's head is even capable of standing up.
Toothy gets his revenge!
That's gotta hurt! And more if the person who bites you has large buckteeth.
"Ahhhhhh!"
"Get it off me!"
"Get this thing off me!"
"What did I do to deserve this?!"
Lumpy at the end of the episode.
It even had a closing iris back then.
