Scavenger Hunt For BD Party For Boss

My boss will be having a bd on March 11th. Last year, we had a visit from SpongeBob and she thinks we can`t top that. We are looking for ideas for a scavenger hunt and small gifts that she will be able to find. This will have to be done either on our lunch break or our 15 minute break. We are looking for something fun and fast. Any ideas? Thanks.
