In Lightning Rod Faces the Cyclops Queen, Wiggleworth had assigned his trusted assistant Squirmgrub to help the Skylanders find the fragments to the Mask of Power. However it was later revealed that Squirmgrub was a traitor working for Kaos, eventually stealing the Mask fragments left at the Eternal Archives and kidnapping Master Eon. In Stump Smash Crosses the Bone Dragon, a furious Spyro lashed out at Wiggleworth for his decision in leaving the fragments in the Archives where the lead Librarian believed they would be safe, and blamed Wiggleworth for Master Eon's capture. As a result of Squirmgrub's treachery, the remaining Mask of Power fragments weren't left at the Eternal Archives but instead were kept at Eon's Citadel. Wiggleworth and the other Warrior Librarians weren't seen nor mentioned again for the remainder of the book series.
Skylanders: Trap Team
When the Eternal Archives became under attack by the Nightmare Villains, Wiggleworth encountered Boris Blisterbottom and attempted to fight the Nightmare Chompy. He was, however, affected by the sleep spell and fell asleep during the battle. Luckily the Skylanders were immune to the sleep spell and saved Wiggleworth from Boris.

In his Trap Team 3DS appearance, Wiggleworth himself has an entirely different design, and only has one set of arms rather than two. His robot's design possibly changed for more pratical reasons, as the book version was many times bigger than the Skylanders.
