A machine operated by the Delightful Children From Down The Lane in Operation: C.A.N.N.O.N., the Delightful Drill attacked the Sector V Treehouse by digging a tunnel through the tree and into the Operation Rooms, where it grabbed the operatives and was about to destroy them when an alarm made them short the "visit". It was destroyed by the explosion of the C.L.A.M.M.A.H. the second time it attacked the Treehouse, sending the Delightful Children flying through the skies.
