A group of students must convince their teacher to give up their strange, definitely-not-a-tadpole class pet in this laugh-out-loud tale, now in paperback!When their class tadpoles are big enough, Mr. Stricter tells his students they can keep just one. The class chooses Bruno, the smallest of the bunch. But Bruno doesn't stay that way for long. Soon, he's grown into a giant, classroom-wrecking creature: he eats desks, he farts for show-and-tell, and he sneezes slime all over everything! Everyone can see that Bruno is trouble. Everyone except Mr. Stricter. With their teacher blinded by his love for the pet, the students must step up and take matters into their own heroic hands.
