How do I wake up the rat?

The rat loves to eat carrots.  Maybe the smell of one would wake him.

There's a carrot on the top of the screen.  You're going to have to shake it
loose.

The cannon, if aimed properly, will do the job for you.  One important
thing to remember is that you can't load the cannon until it's pointed up.

There's a stack of cannonballs at the bottom of the screen.  Find a way
to get one of the balls loose.

Have Warrior punch the stack and get Technician to take a cannonball.

To make the cannon point up, have Warrior punch it.

So load the cannon, and direct it up again.  It's ready to be fired.

All you need to do is use the matches on the cannon and you'll get a carrot.

You're about ready to put the carrot in the pot in front of the rat, but
first you'll need to make sure that the carrot will cook once it's in there.

Light the pot with the matches.

You'll need to use the cannon to put the carrot in it.

Have Warrior punch the cannon up, load it with the carrot, and punch it back
down to make sure the carrot gets in the pot when it's lit.
