Smashers have found an interesting new glitch in Super Smash Bros. for 3DS this weekend. It’s not anything practical to be used in versus play, but it’s good for a laugh in single player. If you eat a giant character (specifically a character that is giant as a result of a special battle) with Yoshi and then let him break out of his egg naturally, the character will keep growing. You can see the bug in action here.
