Mr. Krupp's Dummy is a secondary character of The Epic Tales of Captain Underpants that debuted in Captain Underpants and the Problematic Pandemonium of the Punishing Plungerina.

He later appeared in Captain Underpants and the Worrisome Wedge of the Water Warmongers, which was activated by Harold instead of Mr. Krupp by telling the camp director to put George and Harold in the same camp, but he refused.

He will appear in all episodes in Season 4, 5, and 6.
