Squisher is an orange bipedal ghost with an appetite.
After the Proteus incident, Squisher appeared in Central Park and scared off droves of people in the area. It laughed with glee and consumed hot dogs from an overturned cart. The Ghostbusters were called and they trapped Squisher in routine fashion. Upon further inspection, Peter Venkman became relieved they stopped the ghost in time. It was about to eat a tofu dog and Peter mused its breath would have been deadly.
