Slippery Serpent Forest first appeared in the episode "Escape from Belch Mountain". Jake and his crew travel through the forest in order to stop Captain Hook who plans on throwing Jake's guitar into Belch Mountain. While moving through the forest the young pirates bump into Slippery Serpent. At first glance, the young pirates were wary of the massive snake but they quickly noticed that she meant them no harm but were puzzled how to get past her. The Slippery Serpent allowed Jake and his crew to slid down her back to the other side of the forest allowing Jake and his friends to continue on their journey to Belch Mountain.
