The pupils from the school opposite are having a theme week and are tearing the supermarket apart. Peter traditionally joins in and Titus meets a girl.

Titus and 450 have caught a mouse, which they now have to bring to the Kolinski store in Eimsbüttel. There they meet Henry, Pelle and 450er's crush Kimi. Meanwhile at Kolinski Altona, Flora teaches Mrs. Jensen how to rap, Peter flirts with Pina and Lia tries to make Thorsten a better branch manager.
