Scrapbook Theater

The Scrapbook Theater is a theater in Craft Island in Yoshi's Woolly World. The player can view all 73 of the enemies in the game. In order to view an enemy, Yoshi needs to throw a Yarn Ball at one at least once. The player can also press on some enemies, and they will do a trick. (For example, a Woozy Guy will jump, and a Koopa Troopa will hide in its shell.) The player can also listen to music from levels he or she completed. There are 63 music tracks in the theater (not including "Yoshi's Woolly World Medley", which simply plays a random music track when selected).
