A Puzzling Problem is a HTFF Break.
As Lumpy puts together a jigsaw puzzle, he feels an occasional irritation in his nose and picks at it. He is soon finally left with one more piece. However, he fails to fit it in the hole due to rotating it the wrong way. Then he decides to simply glue it onto the board.
Lumpy's nose irritation returns and he sticks his glue-covered finger into one of his nostrils. The glue causes his finger to be stuck, and as Lumpy struggles to pull it out, he ends up removing his skull. His brain falls onto the puzzle board, which has "Happy Tree Friends Fanon
Break is dead!" displayed on it.
- Lumpy pulls his skull out of his snout.
- The glue bottle Lumpy uses strongly resembles Elmer's Glue.
