Full Synopsis

As a young Boy stumbles upon alone red-and-white-striped hat, its curious owner, the Cat in the Hat introduces the boy to the wondrous world of Seuss ("Oh, The Thinks You Can Think!"). The Cat begins with the story of Horton the elephant who lives in the Jungle of Nool with Jungle Citizens, the Bird Girls, and several other unique creatures. One day, Horton is enjoying his bath when he hears a voice on a speck of dust asking for help ("Horton Hears A Who"). Horton delicately places the speck onto a clover just as Sour Kangaroo and Young Kangaroo bounce along. They inform Horton that there couldn't possibly be a person on that speck ("Biggest Blame Fool"). The Wickersham Brothers join in teasing. The Cat takes on the role of a talk show host and interviews two neighbor birds named Gertrude McFuzz and Mayzie La Bird about Horton hearing things that don't exist. As the naysayers leave, Gertrude stays behind to marvel at the uniqueness of Horton ("Biggest Blame Fool Playoff/Gertrude McFuzz"). The cries of help return and this time, Mr. Mayor and Mrs. Mayor reveal themselves to Horton as citizens of a tiny place called Whoville along with the rest of the Whos. Mr. Mayor and Mrs. Mayor share the joys and difficulties of ("How To Raise A Child"). At this point, the boy from the beginning becomes Jojo, their son, and is blamed for the Cat's mischief. JoJo tries to take his bath, but the Cat isn't done ("Oh, The Thinks You Can Think! - Reprise"). The Cat and JoJo are swept underwater with Fish all around! The tub overflows and Mr. and Mrs. Mayor blame JoJo, but JoJo knows deep down that anything is possible ("It's Possible - Part 1"). Meanwhile, Horton continues to guard the clover despite the other animals' judgments ("It's Possible - Part 2"). Horton and JoJo bond in their imaginations. The Cat wakes JoJo from his dream to tell him more stories, including ("The One Feather Tail Of Gertrude McFuzz"). Gertrude wanted a more extravagant appearance, so she traveled to the doctor for help ("Amayzing Mayzie"). Gertrude begins to take pills and her one-feather tail grows ("Amayzing Gertrude - Part 1"), but Gertrude can't stop there! She takes more pills, and her tail grows longer and longer ("Amayzing Gertrude - Part 2"). As Gertrude leaves, the Wickersham Brothers steal the clover away ("Monkey Around"). Horton chases them through great stretches of jungles, beaches, and sand, but the monkeys hand over the clover to Vlad Vladikoff, a black-bottomed eagle who drops the Whos into a field of clovers. Horton searches frantically for the Whos as Gertrude reappears with a new fortified tail ("Chasing The Whos"). Gertrude tries desperately to get Horton's attention, but Horton is focused on his search for the clover ("Notice Me, Horton"). Mayzie reappears and asks Horton if he would consider sitting on the egg in her nest. Horton agrees ("Mayzie's Exit/Horton Sits On The Egg/Dilemma/ Hunters"). As Hunters approach, Horton, the tree, and the nest fly away ("Egg, Nest, And Tree") and eventually land at Seussby's Auction. Much to his surprise and dismay, Horton is sold to the Circus McGurkus Back in Palm Beach, Mayzie ("Sold/Mayzie In Palm Beach") is feeling carefree... so much so that she's bored! Mayzie heads to the Circus McGurkus where the Cat is the circus ring leader, and Horton is locked up ("Mayzie At The Circus"). Horton pleads with Mayzie to take her egg back, but Mayzie relinquishes all responsibility ("Amayzing Horton"). Horton tells the egg that he'll keep protecting it ("Alone In The Universe- Reprise 1"). He sings the egg a lullaby about the faraway land of ("Solla Sollew") where he imagines JoJo, his family, and all of the Whos. Just in the nick of time, Gertrude McFuzz frees Horton ("Gertrude/ Espionage - Part 2"). Gertrude reveals to Horton everything she's gone through to bring the clover back to him, including having her large tail plucked (All For You). Just as Horton is reunited with the Whos, all the previous creatures take Horton to court for "talking with a speck, disturbing the peace, and loitering... on an egg" ("The Whos Return/The People Versus Horton The Elephant"). Judge Yertle remands Horton to the Nool Asylum and decides that the dust speck be boiled in a kettle of Beezlenut oil. JoJo finally exclaims ("Yopp!"), and the Whos are saved! JoJo is honored as "Thinker Nonstop," and the egg hatches into an Elephant Bird. Gertrude explains to the new creature that Horton can teach him about the earth and she'll teach him about the sky ("Alone In The Universe - Reprise 2"). As the adventures come to an end ("Oh, The Thinks You Can Think! - Finale"), JoJo reappears with the Cat's hat and pulls it over his eyes, ending this story with one last reprise ("Green Eggs And Ham - Bows").
