The adventure starts with Cadence, coughing, saying her prep is going great. Dot comments on her voice, and she says she is fine, and just has been practicing a lot, while still coughing. Dot then suggests getting a smoothie from Franky's. Once there, Dot says Cadence will need to rest, and she will even use force to get her to rest if necessary. Dot asks the player to give Cadence a smoothie, and she drinks it, but is still coughing, despite claiming she is fine. Rory suggests doing a silent show where Cadence "mimes" the music instead. Dot thinks the solution is something hot instead, and asks the player to give her hot cocoa now. Rory says he has an idea, then leaves. Cadence drinks it, then says that worked, but continues to cough. Dot tells her to stop, then considers postponing the show.
Rory returns, saying he found his grandmother's seaweed tea recipe, which helped with his dad's voice before speeches. He says orange seaweed from the Sea Caves is needed, and gives the player a thermos, and says he and Dot will stay with "DJ Can't Sing". The seaweed is scattered around the upper and central parts of the caves. After five pieces of seaweed are gathered, Rory says to heat the thermos in the Crab's Den. There, the thermos is embedded into the wall and heated, but a crab appears, grabs it, and floats away. Rory thinks the smell lured the crab, and says to retrieve the thermos before it is all consumed. The crab is in the Glow Grotto. Rory says to use an emoji depicting royalty, which scares the crab away, dropping the thermos.
Once the thermos is retrieved, it must be brought back to Cadence, who drinks it, and her voice is back. Dot says to send her thanks to Rory's grandma, and he says he will mention it to "her ladyship". Dot tells Cadence to rest, and everything for the Beach Bash is under control. Cadence tries to protest, but Dot says the costumes are almost done and Rory is finished with the confetti cannons. Rory implies he is not done, but Dot again says everything is under control. Cadence is thankful, and says she will see everyone at the show. The player then receives the Fluffy Toque, 100 coins, and 100 Cadence XP.

After gathering the orange seaweed and taking the thermos to the Crab Den, it is heated, but a crab steals it and takes it to the Glow Grotto. After scaring the crab away, it is taken back, and the given to Cadence, where it successfully restores her voice.
