He uses a miniaturization ray to shrink several famous monuments from around the world and uses them to build a miniature golf course in his basement. The following night, The Great Puttinski comes to the Sector V Treehouse and shrinks Numbuh 2 to the size of a golf ball, bringing him to his basement for a "rematch". The final hole of the course is the "Flaming Hole of Doom", which travels into the center of the Earth. Should Rupert get a hole-in-one, the miniaturization ray will fire down the hole and shrink the entire world to the size of a golf ball. Numbuh 2 is used as the "ball", and is shot into the windmill hole, beginning the shrinking process. However, as the windmill continues to spin, he is launched off of it and ricochets off of a light bulb onto a switch on the machine, changing its mode from "smallify" to "bigify". The ray hits Puttkin, causing him to grow into a giant and step on his golf course. Eventually, Numbuh 2, who is still flying around the room, flies into his face and knocks him out. He was also seen at several villain meetings, and in Operation: I.N.T.E.R.V.I.E.W.S., he was in his basement playing golf until his golf club mysteriously disappeared.
