Jiggiwurms have a unique ability that is linked with their giddy jiggy. At a certain point, once they reach maximum giddyness, they unlock the ability to project themselves in the form of jigeists, which are spirit like companions to the Jiggiwurm that allow it to partake in double harmony. How exciting! Sometimes the Jiggiwurm likes to use this special illusion based ability to scare or prank it's fellow monsters.
