When Snowball, the new pet hamster in Ms. Kim’s classroom at Bleacher Elementary School, spends the weekend under a grow-light, sipping on an energy drink, he grows gigantic—and evil. And that’s nothing but trouble ahead for Milton Worthy, especially since his superhero, substitute teacher mom is off on another assignment. Snowball is on a rampage, and Milton has no choice but to team up with Noah, the uber-evil and his arch-nemesis, to stop Snowball before he takes over the school and maybe the world. Will Milton and Noah be able to stop the huge, horrible hamster before it’s too late? Frenemies is the fifth book in a hilarious chapter book series from beloved author of the Silly Dilly songbooks and The Day the Mustache Took Over series, Alan Katz, and illustrated by beloved artist Alex Lopez. It’ll have even the most reluctant readers clamoring for more adventures.
