Where do I get a metal pan?

Try looking around Unseen University.

The cook has one.

Talk to him, and you might be able to get a good idea of how to get it from
him.

He doesn't like magic.

Because too many of the sorcerers around here use it to mess around with him.

Even though you don't know much magic, you can still make his life difficult.

Don't you wonder where that window in the back of the university goes to?

It leads up to the top of the kitchen.

All you need to do is find a way of getting up there.

Look around for a ladder.

There's one on the rooftops of the alley.

Just stand on the square in the alley (the one that glows when you step on
it), and you'll be taken up to the roof.  Then click on the ladder to take
it.

Remember that the cook bragged about how he never lost a pancake?

Well, make him lose one.

Try catching it.

But you can't catch it with your hands.

There should be a net around that you can take.

Look in the psychotrickerist's office.
