Hooray! Wayside School is open again! All the kids from Wayside School had to spend 243 days in horrible schools while Wayside School was closed to get rid of the cows (Don't ask! ). Now the kids are back and the fun begins again on every floor. Miss Mush has prepared a special lunch of baked liver in purple sauce, and it's Pet Day on the 30th floor -- with dogs and cats and frogs and skunks and pigs, and an orange name Fido causing a terrible commotion. In Mrs. Drazil's class, they're throwing a coffeepot, a sack of potatoes, a pencil sharpener, and a light bulb out the window to see which hits the ground first. But the big surprise is that Mrs. Jewls is expecting a baby -- but one named Cootie Face or Bucket Head -- and a substitute teacher is coming -- and everyone knows what that means... Wayside School gets a little stranger!
