You are the fifth team member of the Ghostbusters.

You are on top of a tower and fighting of ghosts. As you are battling the cruel ghosts, you suddenly hear a loud rumbling. The rumbling causes the tower to shake, you almost fall down. The ghosts suddenly flew away and vanished into thin air, leaving you and your other teammates in confusion. You all look at the source of the rumbling, then you see it... the Stay Puft Marshmallow... Girl? Apparently Mr Stay Puft has a sister.. somehow, and she's rampaging through the city! She suddenly spots you with her big blue pupils. Even with her adorable smile, you can tell that she has evil intentions. It doesn't look like she can speak, she can only giggle. "Hehehehe!"
