Big Luma glitch

This glitch can occur when playing as Rosalina & Luma against Yoshi in Super Smash Bros. for Nintendo 3DS and Wii U.

First, Rosalina must acquire a Super Mushroom, then be eaten by Yoshi while still giant. Then, while still in the egg, Rosalina must fall off the edge of the stage and be KO'd while Luma remains alive. When Rosalina respawns, she will be normal sized, but Luma will still be giant and will remain so unless it is destroyed.
