Event 23: Slippy's Invention

You are against Fox and Falco. But Fox and Falco are both equiped with an Invisible Cloak...that never ends! So this battle might be a tad tough. But you can still damage Fox and Falco even though they are invisible all the time. Smash attacks are a good way to defeat them fast. Another thing you can do is fight on the bottom two wings. Fox and Falco sometimes fall of the edge and have a hard time on recovering.
