Megan, Molly and Lickety Split have taken Baby Lofty, Baby Half-Note and Baby Heart Throb to see a concert by a singer named Knight-Shade. The baby ponies quickly become enamored of the glamorous singer and make something of a nuisance of themselves, spoiling the others' ability to enjoy the show and spilling Lickety Split's ice cream cone. After the show, they offer to head back to get a new ice cream for Lickety Split, promising to be quick and come back right after. Backstage, however, they run into a shady zebra named Zeb, who introduces himself as Knight-Shade's personal manager and offers to introduce them to the singer. The three eagerly accept.
Meanwhile, the others start to worry as the babies tarry more and more. When they go backstage to look for them, however, Zeb claims to have sent them home, and so they head back to Paradise Estate as well. Meanwhile, in Knight Shade's camper, a bit of flattery from him and Zeb quickly gets the baby ponies to ask to join the group as backup singers. At Paradise Estate, the adults quickly realize that something's wrong and inform Heart Throb and Lofty, and then head back with them to the concert's site. When they get there, however, the troupe has long since moved on, and decide to organize search parties to find them.
As they baby ponies try out, Zeb activates a device that releases a cloud of smoke that steals the baby ponies' shadows, leaving them tired and washed out and, once they realize that their shadows are nowhere to be found, terrified as well. The main search party, composed of Megan, Molly, Lofty, Heart Throb, Galaxy and North Star, track Knight Shade's group to a town called Muensterville, home to anthropomorphic mice. The mayor reveals that he does indeed know of Knight Shade… just as he traps the party with a giant mousetrap. The baby ponies aren't faring much better, as Knight Shade and Zeb's goons — humanoid mice themselves — quickly round them up and put them in a cage.
