Dick and Sally's boring rainy day at home changes when the Cat in the Hat and his sidekicks, Thing One and Thing Two, burst in and make a huge mess of their house; the Lorax is a lovable creature who speaks for the trees, trying to stop the profit-greedy Once-ler from destroying the forest; a collection of Dr. Seuss' stories about trying something new, discrimination, and stubbornness; Horton, a big-hearted elephant, tries to protect tiny people of Whoville who live on a speck of dust and only he can hear.
