Ella and the Rock Star

Ella, Pat, Tukka, Samapa, and everyone else are about to move to the third grade. But Pat doesn't know the multiplication table and has no intention of learning it. And really, why should he learn it, since Pat is a rock star, and rock stars definitely don't need to know the multiplication table. However, without knowing the multiplication table, Pat won't make it to the third grade, and a rock star who is stuck in the second grade for many years has a pretty bleak future. To help Pat, his entire friendly class transforms into a real rock band. On the way to saving Pat, the friends have to get aluminum, iron, and combined discs (instead of platinum), acquire a yacht for their teacher (a bit old), play a real concert, and figure out what happened to the missing singer Elvira, Pat's main idol. Rock stars, regardless of age, must read this!
