"Previously published in 2000 as Peanut butter lover boy"--Title page verso

Pleskit and Tim swap lunches, leading to unforeseen consequences in this fourth book of the hilarious, fast-paced, and accessible sci-fi series Sixth-Grade Alien from the bestselling author of Aliens Ate My Homework, Bruce Coville. When Tim has a peanut butter sandwich packed yet again, he and Pleskit decide to swap lunches. Tim is pleasantly surprised to find that while Pleskit's squambul smells terrible, it tastes like chicken. But Pleskit has an altogether different experience when he eats peanut butter for the first time. Turns out, he's allergic! And Pleskit's reaction can't be solved by a trip to the nurse's office--he is absolutely, hopelessly lovestruck! Not in his right mind, Pleskit quickly gets into trouble. If he doesn't find a way to fix things, he may have to find a new school--or a new planet!
