Timidclopses is a little one-eyed trickster who is first seen in Crystal Eye Castle in Skylanders: Spyro's Adventure. They meet the Skylanders at the beginning of the level, pushing explosive barrels down the Gauntlet ramp. As their name suggests, Timidclops are very timid and easily frightened. If chased, some may even resort to jumping over ledges (to their undoubted doom) to escape being destroyed. Others will hide behind barrels. They are not introduced in the Wii, but still appear.
In Skylanders: Giants, Timidclopses are seen in Kaos' Kastle and Lost City of Arkus in a similar appearance. However, they are never acknowledged.
