Project on Mythology, creative help needed?

My friends and I are doing a group project on the god Poseidon, and we want to make it really impressive, so we decided that at the end of the presentation, we would give everyone like a small something representing Poseidon. The problem is we can't figure out what to give. Anything really nice is like expensive to buy thirty-five of, and hand made stuff looks kinda bad. Any ideas would be greatly appreciated. :)
