Somewhere beneath the Hogwarts lake

Slytherin hid a giant snake

"Couldn't you simply go on and bake"

Godric asked, "A delicious chocolate cake?"

Slytherin said: "A cake I won't make!"

As it turned out, he was allergic… to chocolate cake.

This has less to do with the second book then I would have liked (okay, it has nothing to do with it), but it came out pretty well (sort of). Constructive criticism is greatly appreciated. Flames will be used to give the central heating a break.
