Player is frozen flag. This includes controls and animation. Other sprites still move and can interact with the player, but contact with them should be avoided, as it would freeze the game. This may be useful for cutscenes to eliminate the jumping sound.
Mainly used for the Yoshi growing animation from a baby to an adult, as well as while Yoshi is laying an egg or eating a berry. It's also used during the keyhole animation and at the start of Morton/Roy's fight.
