The Ren and Stimpy Show: Stimpy's Invention is an action-adventure game for Sega Genesis based on Nickelodeon’s animated series. The story centers on Stimpy’s Mutate-O-Matic exploding and scattering pieces across the neighborhood.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• Playable as Ren or Stimpy, with character-specific attacks like Ren’s fly swatter and Stimpy’s hairballs and bath towel.
• Team-up moves include rolling Stimpy like a bowling ball and spinning Ren’s ears to fly upward.
• The game features six city scenes plus a maze of sub-levels.
• Familiar enemies and cronies include Lump & Loaf, Kodiak Marmosets, Cabbage Heads, and the Walrus.
• The adventure travels from Mr. Horse’s over-populated refrigerator to outdoor areas filled with hazards.

This Genesis release adapts the offbeat Ren and Stimpy cartoon style into side-scrolling action built around character swapping and cooperative-style moves. It sits alongside other 16-bit Nickelodeon game releases from the early 1990s era.
