They are known as Ghosts by the people who used to go to the park, but they expelled everybody and now the Ghost Toasters will save the place. It’s up to the main characters of the Regular Show online games, being them Mordecai, Rigby and Muscle Man to watch every important point of the public area and find the weird guys in suit to get rid of them. They simply shoot water balloons of others full of paint on people, who scared get away and never return. This is bad for their business, as Pops sells things there and need clients. Fortunately, you may join one of the characters to battle against them in some kind of new prank war, this time available for the computer for free, using nothing but the Mouse to drag the character out of their aim and then shoot you at the Ghosts.
