From the Super Mario Wiki
The Woodpecker

The Woodpecker is a souvenir located in the Toys folder in WarioWare: Twisted!. It features woodpeckers (controlled by the player) who perch themselves on an infinitely-long tree and peck at it. The strength of their peck is based on how hard the console is twisted. Once enough of the tree is pecked out, it collapsed on top of the woodpecker and the screen pans down to a different section of the tree with a different woodpecker. Occasionally, the tree will be replaced by a steel pole, and two woodpeckers on either side of the pole will peck at it until it collapses. The time of day cycles between early morning, noon, and afternoon.
