Underwater Birthday Ball
A play for the very young
A Please Touch Museum and Philly Children’s Theatre production
April 2 – 27, 2025
Free with Museum admission
Join Aster the mermaid and his ocean friends for a magical celebration beneath the waves!
Before Aster sets off on his journey to clean up the seven seas, he’s throwing a birthday ball like no other.
His guests — Big Fish, Little Fish, Jellyfish, Shark, and Turtle — are feeling nervous to attend the party for different reasons and the story follows their journey to find the courage and confidence to go down deep. The show includes live acting, singing, dancing, and puppeteering to narrate the story as well as an original score.

See the show in April at Please Touch Museum!

At Home Activities
Continue exploring your creativity after the show with these activities you can do at home, using the items in your swag bag from the show, plus some common household objects.
-
Paperbag Puppets
Suggested Materials: Paper bags, markers, crayons, glue, googly eyes, yarn (for hair), fabric scraps (for clothing), recycled materials (i.e. cardboard, bubble wrap).
In the show, we saw lots of puppets like Big Fish, Little Fish, Jellyfish, Shark, and Turtle. Now it’s your turn to make your own puppet using the colorful paper bag that your items came in! You can turn your bag into an underwater sea creature, an animal, a person, or even a totally made-up monster. Use whatever supplies you have to decorate your puppet.
Once your puppet is ready, you can put on your very own show. Make your puppet talk, move, and even sing! You can create a story and bring your puppet to life just like the actors do in the show.
-
Egg Shakers
Time to shake and dance to your favorite music! Start by playing your favorite song, and shake your egg shaker along with the music! Try shaking it slowly to a slow song, and then speed it up when the song gets faster. You can shake your egg shaker up high, down low, and even in a circle!
Here’s a fun challenge: Turn on the Shark Shake song from the show! This song is both fast and slow. Can you use your egg shaker to follow along as it changes?
-
Ribbon Rings
Let’s pretend to be jellyfish swimming in the ocean! Grab your jellyfish ribbon ring and get ready to dance! Twirl the ribbons around as you imagine you’re a jellyfish floating through the ocean. You can make your ribbons move in all kinds of ways, just like jellyfish float and swim.
Let’s play a game: Imagine you’re swimming from your home at the top of the ocean down to the sea floor. What would swimming up look like? What about swimming down? Now, use your whole body to move with your ribbons—twist, sway, and twirl like you’re floating in the ocean!
Can you follow the follow-along song while dancing with the ribbons? Let’s see you jump, shake, and groove!
-
Sea Shells
Paint or color the sea shells!
Time to make your sea shells colorful! Take your beautiful sea shells and get ready to paint or color them with markers! You can use bright colors, glitter, and designs to make your shells look extra special. Once you’re done, you can even use your painted shells in your puppet show or use them for your own ocean adventure.
-
Create a Play
Use your paper bag puppet, seashell, ribbon ring, egg shaker and whatever other objects or toys you have at home: make your very own underwater play. Here’s how:
- STORY: Start with a story! What happens in your ocean world? Maybe the jellyfish go on an adventure to find a hidden treasure, or the sea creatures work together to solve a mystery.
- CHARACTERS: Choose your characters! Pick what characters are part of your story and what part they play in your underwater play.
- MUSIC: Add music! Pick what kind of music to have in your play. You can play your favorite songs or use your egg shaker to make your own. You can also use the following link to use two songs from the show: Shark Shake and Follow-Along Song.
Lights, camera, action—it’s time to perform your show for your family or friends, or even an audience of stuffed animals! Don’t forget to use all your amazing creations to bring the play to life!
Music
Sing and dance along with two of the songs from the show: Shark Shake and the Follow-Along Song!:
Discussion Questions
- Little Fish was very nervous about going deep to the ocean floor. Have you ever felt nervous about trying something new? What are some ways you were able to do the new thing anyway?
- Jellyfish was worried about dancing and hurting a friend with his many stingers. What helped him feel more confident? What is something you could say to Jellyfish to help them?
- Sea Turtle had the coolest dance moves. Can you teach your favorite dance move to someone? Maybe they can teach you a dance move too!
- Shark is Aster’s teacher and gave Aster advice when he was feeling nervous about his adventure. Who is someone you can talk to for advice before or during a big change in your life?
- Aster the Mermaid is going on an adventure to help clean up the ocean. What is something kind you could do to help nature?
- If you could invite any sea creature to a party, who would you invite and why?
- What would you do if you were a mermaid for a day like Aster?
- What kind of sea creature would you be if you lived in the ocean?
- After the Birthday Ball, what do you think should happen next in the story?
