Party food ideas:

For the punch bowl, use blue kool-aid & sprite with gummy sharks frozen in ice cubes to look like fish swimming around!

Set out a bowl of fish-shaped crackers for your guests to snack on during the party, or as an appetizer while you prepare other snacks.

Fish Themed Decoration Ideas:

Hang blue and green streamers lengthwise from the ceiling to simulate the ocean - the kids love to run through them. Other ideas include cutting out the silhouettes of waves out of blue poster board, hang around the room to create the ocean. Buy a few rolls of fish themed wrapping paper and cut out the fish. Glue on the posterboard so that they are “swimming” around the party room.

For your favors, fill a themed goodie bag with goldfish crackers, a water toy, fish shaped fruit snacks, bubbles, novelty sunglasses or swim goggles, swimmies or other pool toys!
