The Big Nap (Chet Gecko Series)

Is it just Chet, or is everyone acting just a little bit ? One by one, the students at Emerson Hicky Elementary are becoming mindless goody-goodies. No one talks in class, no one complains about homework—heck, the line to clean the chalkboard erasers is out the door! Everyone is acting like . . . well, a zombie. Chet loves a good nap—but this is one he's got to avoid at all costs. Can he save the school? Or will Chet and Natalie be the next in line at the chalkboard?
