Dororon is a mud sprite living in Shizuku Forest, acting as the main prankster within Shizuku-chan's circle of friends. His signature mischief involves tossing mud at others during playful antics. Though his pranks often cause minor chaos, characters like Shizuku-chan hold affection for him, valuing him as an integral part of their group.

His portrayal stays consistent across the "Pururun! Shizuku-chan" anime and its sequel season "Pururun! Shizuku-chan Aha." Episodes such as "Aha" 5 to 8 emphasize his prankster role, where his actions fuel comedic scenarios and small adventures. One special segment features a birthday celebration for Dororon within its context.

Details about Dororon's origins, family background, or character development arcs are undisclosed. His portrayal and potential expanded roles in the "Picchipichi Shizuku-chan" series, "NiJiRo Fairy Shizuku-chan" spinoff manga, movies, OVAs, or other official media beyond the main television anime seasons remain unspecified.
