Event Match 23: Slippy's Invention is one of the 51 Event Matches from the Event Mode in Super Smash Bros. Melee. You are against Fox and Falco, but Fox and Falco are both equiped with a Cloaking Device that never ends. As a result, this battle might be slightly difficult. Despite being invisible, Fox and Falco can still rack up damage percent (otherwise, this event match would most likely be much harder) Smash attacks are a good way to defeat them fast. Since Fox and Falco sometimes fall of the edge and have a hard time on recovering, use edgeguarding techniques to your advantage.
