Right on cue and underscored by heroic music, a Superman-esque announcer (Martin P. Robinson) says, "Look, in the sky! Faster than a speeding mommy, nicer than a friendly doggy, it's a plane, it's a nurse... it's Super Nanny!" Hearing the distressed cries, Super Nanny heads to Sesame Street to be cheerful, sing songs, and clean up.

Oscar jeers that she can't possibly clean all that up with her feather duster. Super Nanny insists that it can be done as it's a super feather duster, showing different ways she can use it (as a baton, a bouquet, or a tickling implement, among others). She then claims it also doubles as a magic wand, and proceeds to show Oscar.

Oscar regrets opening his big mouth, but he's even more appalled when he looks closely at his clean trash can: curtains everywhere, no furniture in the swimming pool, a Princess phone, and track lighting. Irvine laughs at her uncle's neat look, while Oscar bemoans the fact that 24 years of work have been destroyed. As the last straw, Fluffy's trunk surfaces from the can, adorned with pink ribbons.

Oscar asks Gina to intercede for him, noting that if he weren't a Grouch, he'd go so far as to say "please." Gina talks to Super Nanny and explains the essential cultural and physical differences between Grouches and people, explaining that Grouches take extreme pleasure and pride in amassing a mess. Super Nanny finally realizes she remodeled Oscar's house against his wishes without even asking.
With her newfound multicultural awareness, Super Nanny utters another "Alakazam!" and restores the status quo. Oscar admits that Super Nanny isn't "so bad for a neatnik." Penny Pipkins returns the compliment and tickles Oscar, who asks her to keep it up. Oscar opines that "This could be the start of a beautiful mismatch."
