The Blissworm is a fictional animal character from Conner Bailey's short story, "Galaxy Queen". It was 'adopted' by Alex Bailey and brought to the Otherworld with Conner's other fictional story characters. It was described as extremely cute and adorable, hence the name. The Blissworm has four small 'hands', a small, plump body, black button eyes, and a constant smile. According to Conner, it is always happy, no matter what the situation. This is repeatedly evident; for instance, during Conner and Alex's visit via Portal Potion to "Galaxy Queen", when the Blissworm is captured by Polycrabs, it simply waved at them and blew them a kiss. It is apparently unable to have negative emotions and feelings; either that, or it is too consumed with its never-ending happy state to realize its danger in such a situation.
The Blissworm has four small 'hands', a small, plump body, black button eyes, and an ever-constant smile. In the sixth book of the series, Worlds Collide, the Blissworm created a cocoon and underwent a metamorphis to become a Mad Moth.
