The handler for the monster (IDs 36 and 37), which pops up out of one of the dustbins at the bottom of the screen (it is created by CreateMonster). Byte 6 of the actor is its state, which chooses which code at HandleMonster_Rising is run using the table at MonsterStates. If a flour shot hits the monster it is coloured white (see TestFlourCollision), the points are added to the score, and it goes straight to the state in which it drops back into the dustbin.
