How do I get the piece of cheese?

Hint 1 of 6:

You can't.  But you can make something out of it.

Hint 2 of 6:

To get there, you'll need to use the catapult in the near position.  Both
characters can reach the cheese that way.

Hint 3 of 6:

Start by sending Ooya over.  Have him cast a spell on the cheese.
