They're lean, they're mean, they're the pride of Stoneybrook. Who are they? They're Kristy's Krushers!

When Kristy sees how much her little brothers and sister want to play on a softball team, she starts a ragtag team of her own. Maybe Kristy's Krushers aren't world champions (how could they be, with Jackie Rodowsky, walking disaster, playing for them?), but nobody beats them when it comes to team spirit.

Now Bart's Bashers have challenged the Krushers to a game. It's bad enough that the Bashers truly are lean and mean — but what's worse is that Kristy has a crush on the Bashers' coach!

The Mancusis don't have any kids... but they sure do have a lot of pets! So when they're desperate for a sitter, who do they call? The Baby-sitters Club! Kristy feels pretty sure that the BSC does not pet-sit. But Jessi has always liked animals, and she talks Kristy into being okay with her taking the job.

With snakes on the loose and sick hamsters, Jessi's got plenty of pet-sitting troubles, and things don't get any easier when she and her friends get into a big fight. Will Jessi be able to handle her pet-sitting job when things are going wrong with the baby-sitters, too?

Stacey is so excited! Her friends from The Baby-sitters Club are coming to New York City for a long weekend. It's going to be perfect — a party and a sleepover on Friday night, a big baby-sitting job on Saturday, and lots of sightseeing throughout.

But it turns out that the baby-sitters are way out of place in the big city. Mary Anne sounds like a walking guidebook, Dawn is afraid of everything, Kristy can't keep her mouth shut, Claudia is jealous of Laine — Stacey's New York best friend — and Mallory and Jessi feel intimidated by Stacey's classmates. With ten kids to baby-sit and a full schedule of activities, how will Stacey keep the weekend from becoming a complete disaster?
