The microgame "Wario Wear" has unused graphics of a naked Wario, whereas the released version features him wearing an undershirt and underpants at the start of the microgame.

The game had been developed in secret without even the manager knowing about it. It was however approved after it had been revealed.

9-Volt's microgames feature classic Nintendo toys from the 60's and 70's. These toys include the Ultrahand, Chiritorie, and others that were made years before Nintendo became a video game company.
