Spiritweed is a horrifying and scary ghost guppy.
Spiritweed is very mean - if he sees a fish, he has to use his Confusion Ray on it; if he finds a good Bubble Guppy, he has to possess him; and if there's a haunted house around, rest assured he'll be spooking in no time - but he's made friends with all the other ghost guppies anyway.
Spiritweed's super-charged frightening energy and insatiable ghoulish curiosity make him great at scaring others. He'll be sure to deliver some ghostly slapstick humor along the way. He's often the subject of a continuing joke that repeats during the episodes.
Spiritweed has light pink skin; green and light green eyes; spiky, light green hair; and a light green tail.
