Blossom Valley is opening a brand-new community center, and Layla and her Bots are playing at the opening, but the mayor is worried because not many people have signed up to come to the party; so Layla and her bots decide to build a cupcake machine to attract a crowd--but they are uncertain how to manage the variety of decorations proposed. Includes a DIY activity that readers can try at home.

Layla and the Bots visit the Surfside Rescue Center, where they meet a dolphin named Splash, who will only eat when the music is playing, but is very picky about the music--so Layla and the Bots build a machine that uses the sound waves Splash communicates with to change the music.
