Mutant potato Rot and his friends team up for a super-sneaky mission in this third installment of the hilariously silly graphic chapter book series from the bestselling creator of the Narwhal and Jelly books.

Rot’s older brother Snot is always sneaking up and scaring him, and Rot has had enough. He’s determined to scare the snot out of Snot for once! And that means Rot is going to have to learn to be sneaky, maybe even…the sneakiest in the world!

But when being the sneakiest spud proves a lot harder than Rot thought, he realizes this is a mission he can’t do alone. Can Rot and his Not-So-Sneaky Super Secret Spy Squad find a way to use their uniquely unsneaky skills to pull off a spud-tacular scare?
