Elroy is a magical talking dancing ukulele who in a friendly fashion helps Mindfreak through her adventures. After Mindfreak joined S.T.U.P.I.D. , Elroy's soul was transferred into an actual ukulele, so he can no longer subconciously help Mindfreak. Elroy communicates with the other S.T.U.P.I.D. members by having someone strum him.
