Root Awakening is a secret minigame in WarioWare Gold in the game's Toy Room. Its name is a pun on "rude awakening". In it, 2 to 4 players must take turns picking objects from the mandrake of varying value: leaves are worth 30 points and have a danger level of "mild", flowers are worth 50 points and have a danger level of "medium", and golden-colored apples are worth 100 points and have a danger level of "high". If a player picks an object that wakes up the mandrake, they instantly lose 500 points and the game ends, with the winner being the player(s) with the most points.
