Stink and the Freaky Frog Freakout

After a close encounter with a mutant amphibian makes him freaky for frogs, water-shy Stink becomes a swimming success. Stink may be super smart, and Stink may be uber clever, but he's been in the Polliwog swim class frog-ever and he still can't bear to put his face in the water. Why would he want a geyser up his nose, on purpose?
