Paul was standing in the bathroom in leather pilot's gear, because of his previous changes his skin and his clothing were mostly metallic grey, his eyes and mouth were turned into cartoon versions of themselves and instead of his nose, he had a propeller.
Tag on the other hand was wearing a shiny blue armour with a rocket pack and had a few details in his private area changed. Otherwise he was quite normal, holding what looked liked the remote to an RC plane.
"Now let's try the Landing Gear knob, shall we?", Tag asked the pilot who nodded, trying to mentally prepare himself for whatever would happen next. As he turned the knob counter-clockwise the boots changed. The foot parts of them changed into a round shape like narrow cylinders. Paul's crotch area underwent similar changes. There his ball sack was rapidly increasing in size, merging with his pants, forming a round cylindrical shape. Meanwhile the substance of his feet and boots has changed into a black rubbery mass. A profile started to appear on them forming full wheels. He burst out in a moan as his member quickly erected. Tag stopped there for a moment as Paul regained balance on his new wheel feet, "Are you alright?". Heavily moaning, the pilot nodded, and Paul went on turning the knob. Degrees later the member merged with the belly as the new wheel separated from his body now only dandling on his hardening member. The wheels on his feet finally have fully formed and were held at their hubs by the ends of his legs bending to the inside. Instinctively turning on the brakes, Paul tried to walk a few steps. Succeeding he became a bit more courageous and released the brakes trying to skate. Distracted by surprise he nearly crashed into Tag.
