Event 23: Slippy's Invention
The player is faced against Fox and Falco on the Venom stage, but Fox and Falco are both permanently invisible. This transformation is the clear transformation also used in Invisible Melee, rather than the Cloaking Device, so Fox and Falco can still be damaged. The stock icons for Fox and Falco appear darkened to indicate their invisibility.
At the beginning of the match, Slippy says, "How's the cloaking device I invented?" The communication with Slippy begins shortly after the announcer says "Go!"
