OMG, you really are from England, you called a diaper a "nappy".
Anyways, Uberchu has cold, so he can't smell...
I trap Uberchu in a room with, SHARKZ WITH LAZOR BEAMZ ON THEIR HEADZ! This time, I make sure to fill the tank with salt water, and put in working batteries on the LAZOR BEAMZ! The batteries are also water-proof. Uberchu's Teleport can't be used anymore, as well.
