A Banana Peel is a key item in Gregory Horror Show: Soul Collector. It can be obtained by eating a banana.
The player can set the banana peel on the ground pretty much anywhere. Anyone that steps on it will slip and fall, rendering immobile until they get up. The player will also slip on it too, which can be dangerous when a guest is chasing him/her. The Banana Peel is required to steal Catherine's soul.
