Time to kick back and relax with a nice cold drink of milk! For this part of IAIM the Ice Arrow is hidden in the Milk Bar.
Along the wall where the entrance is are three giant [milk?] tanks. Hidden within the right most one is a crystal switch the player must activate in order to spawn the chest. Normally very few items can be used here so this restriction was removed. The switch is still within the tank however that can not be shot (glitchlessly) and requires a bomb to hit it.
The Collision
Normally the collision around the bar extends very high up. It was lowered, but still not enough to climb over it. A hookshot target is then added to the ceiling behind the bar to allow the player to reach the chest.
