Jumbo Candy is a power-up that appears exclusively in Kirby Mass Attack. When this item is used, all Kirbys the player currently has grow to an enormous size and temporarily become invincible while rapidly flashing different colors. While under its effects, the Kirbys can break Star Blocks without having to be flicked at them. The Kirbys can break Metal Blocks as well, and defeat all enemies they come in contact with. The only downside to this is that they kick away keys and Treasure Chests if the Kirbys touch them.
After chomping down some Jumbo Candy, don't rampage too wildly.”
