How many big yikes can you fit into one party?

Lisi’s parents are hosting a party celebrating their wedding anniversary – and they’ve invited Cathy, too. She’s even allowed to stay for a sleepover in their basement party room! While Lisi is stressing out, Cathy is super excited, especially when Lisi’s cute cousin shows up. Is he really flirting with her?!

What on earth’s going on? One thing is for sure: It’s total chaos!
