I've given the loner "sunglasses", "wild hair", the "artist's smell", and I've covered him in glue, but I still can't get him to the artist.

I've also gotten the virus on the computer, but I've had no luck with the game.

I've given Crasto the cheese, but I haven't gotten it back.

Here's what I have to do:

"Your ultimate goal for the day is to get out of school. Before you do, however, you're looking to get your bag out from the classroom where you left it.

That is, however, not the only thing going on in school today.

Mrs. Laurente has revealed herself to be some kind of a secret agent. She's asked you to get for her the fingerprints of Mr. Martin, computer lab technician, and the tooth marks of Mr. Crasto, librarian.

There's a major fight going on between two English teachers on the girls' side, and you've got to find someone to help you stop it before the teachers kill each other!

You've been assigned to take care of a class of younger students. The class is wild, and you're struggling to figure out what to do to keep them quiet.

You've uncovered a major power struggle in the Chemistry Department, where Mrs. Desai is brewing a potion to give her full control of the lab. She's asked you to get for her gold, methanoic acid, and nitrochalk. So far you've given her the gold.

The teachers in the physics lab have built a time machine, and they want you to go back in time to get some "dead organic matter." All you've really learned so far is that they definitely do not want leaves.

You've run into an art student who's convinced she's the only artist in the school. She's looking for another artist -- someone who looks, sounds, and even smells like an artist.

Hungry Mrs. Awatif is looking for something wriggly to eat and wants you to help her out.

Mr. Anand over at the computer lab is having trouble with a game and is looking for your help.

Mr. Crasto walks in from the main library. "Keep quiet now!" he says and lingers for a few seconds. Then he goes back to the main library."

Thanks for any help!
