• There is a way to upgrade the Annihilator with the gumball.
• There is an achievement for having the WW, monkeys, and Ray gun. Maybe teleport holding them. Use each teleporter maybe it will change the wall lights.
• Maybe shoot the hanging man, clock at mainframe, robot head, plane, or any other objects that could be shot at with the upgraded annilihator.
• Buy staminup and use the gumball that allows you to shoot while sprinting. Maybe use both and shoot at the robot.
• The gun that is on the summoning key pic Easter egg, maybe double pack it until you get the thunder gun effect and shoot at the robot or plane.
