Gill Grunt was a brave soul who joined the Gillmen military in search of adventure. While journeying through a misty lagoon in the clouds, he met an enchanting mermaid. He vowed to return to her after his tour. Keeping his promise, he came back to the lagoon years later, only to learn a nasty band of pirates had kidnapped the mermaid. Heartbroken, Gill Grunt began searching all over Skylands. Though he had yet to find her, he joined the Skylanders to help protect others from such evil, while still keeping an ever-watchful eye for the beautiful mermaid and the pirates who took her.
Elite Gill Grunt was released with the first year of Eon's Elite characters which came out with the Trap Team game. He is exclusive to GameStop.
