Crafting Activities:
- Create Pool Noodle Fish
Check out this tutorial on how to make a pool noodle fish by Happy Toddler Play Time. The fish is made from a slice of a pool noodle, pipe cleaners, and googly eyes. And the best part about this craft is that it can be put in the water! After your guests make some, have them float them in a pool of water for an interactive craft. - Create Turtles using Paper Bowls
Have your guests use paper bowls and construction paper to create their own turtles. To create the turtle, turn the bowl upside down to make the turtle’s shell. Then, use the construction paper to craft the turtle’s legs, tail, and head. Tape all the pieces together and paint it to look just like a turtle. - Create Jellyfish with Paper Plates
Another craft you can make with paper plates is a jellyfish. Cut the paper plate in half to make the jellyfish’s body and then tape paper streamers to the cut side for the tentacles. Then, just add some paint and googly eyes and your guests will have their very own jellyfish.

- Coral Reef Painting with Sponges
If you’re looking for a painting activity to do at your party, then have your guests make a coral reef with sponges.
