Bernie

Bernie is one of the four main characters in the series. He is a clawless hermit crab who lives on the Volcanic Island with his best friend Zig. Comparatively, he is smarter than Zig. He is often seen making gadgets and devices to help Zig get Marina the mermaid. Despite their occasional squabbles (such as when Zig tried to eat him or when he takes advantage of him), Zig and Bernie show that they care for each other very much. Zig makes Bernie happy at times and vice versa. His girlfriend is the starfish on Marina's hair.
