Change vacuum power
There are three different medals you can collect to change the powers of the Poltergust 3000 vacuum cleaner. They are the Fire, Ice, and Water medals. When you collect the Fire Medal, you can suck up ghosts that have a ring of fire around the health hearts. Also, you can press L to spray fire from your vacuum to light candles and hit ghosts with a ice health meter. When you collect the Water Medal, you can extinguish flames that are too powerful for your vacuum to put out. Also, you can press L to spray water.
