Stanley is forced to sell Putterware to pay off a bill that The Mask ran up, and Peggy goes undercover to unearth a disgusting secret about the product and the CEO, one Miss Celia N. Airtight.
Tropes:
- Anthropomorphic Food: Celia N. Airtight brings food leftovers to life so that she can get revenge on those who fired her.
- Attention Deficit... Ooh, Shiny!: The Mask as usual decide to go after the people who were jerks to Stanley before rescuing Peggy from the mutated fish leftovers.
- Big Eater: The Mask turns this into a weapon as he uses it to defeat the leftovers.
