The Hullabaloo Bugaboo Day by Sheree Fitch

Upper Millidocket Elementary School is an exceptionally lovely place to be. The children are excited to learn, the teachers are excited to teach, and the school secretary holds everything together. But when Mr. Tiggle, the principal, forgets to recite his daily poem during the morning announcements, everything goes upside down. Miss Argyle, the school secretary, disappears (and decides to stay disappeared for a while), tarantulas escape their cages, and the school comes very close to falling completely apart. A second edition of a Sheree Fitch classic with new illustrations from Kelly Ulrich.
