The I.T.S.I.B.I.T.S.Y. is a spider-shaped vehicle that can shrink to microscopic size. In Operation: S.P.R.O.U.T., it was used to remove a brussel sprout from Numbuh 4's body. It is equipped with cables that can be attached to objects that need to be moved. Since the KND used the cable mechanism to escape Numbuh 4's brain, Numbuh 5 had to manually attach them to the brussel sprout by herself.
