What are the names of towns in Dr. Seuss books I know Who-ville but there more?

You're right, there are more than just Who-ville! Here are some other towns mentioned in Dr. Seuss books:

* Snizzle-Fizzle-Bertram-Bingle-Boing-Boing: From "The Cat in the Hat."

* The Lorax's Town: From "The Lorax" (it's not named, but the Lorax lives there.)

* The Wickersham Brothers' Town: From "Horton Hears a Who!" (Not named specifically, but it's the town Horton flies over.)

* The Grinch's Cave: From "How the Grinch Stole Christmas!" (This technically isn't a town, but it's a distinct location.)

* The Sneetches' Beach: From "The Sneetches and Other Stories"
