In 9-Volt's "8-Bit Hero" microgame the player has to find the wrong pixel in a zoomed sprite from a Nintendo game. In Level 3 the image is Popo from Ice Climber. Note that in the brief scene from Ice Climber that plays after the microgame is won, the Topi enemies appear in their original japanese look (that of a seal) even in international versions of WarioWare: Touched!.

9-Volt's "Ice Climbers" microgame is based on Ice Climber.
This microgame returns in WarioWare Gold as one of 5-Volt's microgames in the Mash League.
Additionally, one of the premade objects usable to create original microgames is the Eggplant from Ice Climber.
Copyrights for both series are held by Nintendo.
