Often accompanying tradespeople, Doubleep enjoys following its Trainer around and carrying their tools with its many ribbon-like hands. Its grip is so tight that it is impossible to steal an item from Doubleep, unless it willingly hands it over.

It disguises itself as seaweed by making its tentacles sway. The complex attack patterns of its two swords are unstoppable, even for an opponent greatly accomplished at swordplay.
