Super Smash Brothers Reference
During the game, you will encounter Master Hand, who is the boss on Super Smash Brothers and one of the bosses on Super Smash Brothers Melee. After you kill him, he gives you Smash power, which gives you several abilities mixed up. However, these abilities are in the same control sequences and combinations as Kirby's controls for Super Smah Bros.
