Man, worms are much more vicious up close!

Stealing the Diamond
Henry uses the shrink ray to shrink himself and pass through a hole in the Museum's wall. He gets shrunk to the point where he becomes smaller than the grass and is then attacked by a worm, which is giant from his perspective.

Trivia

 * Before the worm devouring or murdering Henry, the sound made by the worms is the "WRYYY!!!" scream from JoJo's Bizarre Adventure, where it is uttered by the villain Dio Brando. Specifically, it hails from the 1998 fighting game JoJo's Bizarre Adventure: Heritage for the Future.
 * Puffballs admitted he never knew it was from JoJo and just thought it sounded funny.
 * It is a copy of the Shrink n' Grow and Grow 'n Shrink.
