A fun beginning to your undersea party allows your guests to fish for a name tag! Make a fish-shaped name tag for each guest using thick, colorful paper. Decorate with markers and attach a paper clip to the mouth of each fish. Place all the fish in an empty kiddie pool or decorated box. As each guest arrives, hand him or her a fishing pole (sturdy stick with a yarn “line” and a magnet “hook”). When a fish is “caught”, write the child’s name on it!
