I need to give out souvenirs related to the theme "Ahoy!". Any ideas?

Question

It is for a school campfire. The souvenirs would be given to our guests.

Answer 1

How about using Nautical things like anchors, sailors hats, boats and such.  Unless you want to clarify question that's the best I can do.  Any thing related the ocean (cruises etc.)

hope this helps

Answer 2

It is rather a vague description. If it were for a child's party, toy boats, plastic bubble pipes, maybe wash off tattoos. Is it for boys or for girls?

For adults? Miniature "Keg" decanters marked with rum, pipes, a brass bell.

Without knowing more specifics, it is difficult to accurately answer.
