Adam's birthday sleepover goes awry while Barry and Erica compose a song to get Murray to appreciate music.

When Adam thinks he can harness some of Pop's luck, he ends up losing his toys on a gamble; Erica's dream to dance on a TV show is derailed when Barry gives her pink eye.

Beverly asks Miss Cinoman to let Adam -- who is going through puberty -- lip sync in the school musical. Murray inspires Erica to go to the homecoming dance with Geoff Schwartz.

Barry's dream of having a dog comes true, but he's disappointed when the pup takes an immediate liking to Murray. Beverly is upset not to be included when Erica and Lainey plan a girls-only sleepover.

Beverly forbids Adam to see the movie "Porky's," so Murray pushes him to break the rules. But the plan backfires when Beverly forbids Adam to use the phone for Valentine's Day. Meanwhile, Barry tries too hard to impress Lainey for the holiday using the music of Lionel Ritchie.
