Dumb Bunnies is a series of books created by Dav Pilkey, the author of Captain Underpants, under the pseudonym "Sue Denim".
The Dumb Bunnies did everything in reverse, including sleeping under beds and putting flowers upside down in vases.
The series is said to be mocking or parodying books like Good Night Moon by Margaret Wise Brown and The Stupids Step Out by Harry G. Allard and illustrated by James Marshall.
At the end of the book, a picture on the back cover shows her coming out of a sewer pipe and landing in a lake.
Note: The cover originally had the word "spam" on the bowl of porridge, which Pilkey claims was meant to be a joke, until the Hormel Foods Corporation threatened legal action, causing either a recall of the book or placing a golden sticker on it until a reprint was made without the word.
But then the sun comes out and they think it is bad weather, so they head to the movie theater (accidentally stealing a car in the process).
As they leave the zoo (the book says that they decide to go home, but they really got kicked out by the zookeeper), they come across two giant apes which they mistake for being "Free Kitties" (the box that the words were written on did contain real kittens, but when the apes climbed over the wall, they scared all the kittens, and the owner who carried the box, away).
They return home at the end of the day and get into their new waterbed (with a series of hoses spraying water on the bed) and fall asleep.
In 2010, The Dumb Bunnies Go to the Zoo was placed on the "Most Challenged Books of 2010" list that was published by the Canadian Library Association.
