In the 1977 television special Halloween Is Grinch Night, which implies that the overlook is located on Mount Crumpit, additional geographic features are added to Whoville such as Punkers Pond, where sea monsters known as Hakken-Kraks (an apparent play on the legendary kraken, and reference to one of the many creatures from his book Oh The Places You'll Go) reside.

In the 2000 live-action film adaptation Dr. Seuss' How the Grinch Stole Christmas, from Universal Pictures and Imagine Entertainment, Whoville is located inside a snowflake, south of Mt.

The Whos are whimsical, human/leporid/kangaroo-like hybrid creatures who live in shaped houses, known for their warm hearts and welcoming spirits.

Just north of Whoville, atop a high mountain, Mount Crumpit, a bitter, cave-dwelling creature named the Grinch lives with his dog, Max.

In the 1987 Soviet Ukrainian animated Horton Hears A Who short by Kievnauchfilm titled My Friends, Where Are You?, the Whos resemble tiny yellow elves with pointy noises and cone shaped hats.

[2] In the 1992 Horton Hears A Who Russian animated short titled I Can Hear You!, the Whos are identical to humans and live in a simple agrarian society where they mow grass, work in the mill and rear chickens and horses as microscopic as they are, and Whoville is shown as a small village rather than a city (in contrast to the Jungle of Nool which seems to be a pastiche of 80's Soviet city life with occasional appearances of modern technology).

Also, they are shown to be very greedy and materialistic as compared to the book version, making them more distraught initially when discovering their presents are gone.

In the 1970s animated special Horton Hears a Who!, rather than a mayor he is a professor of Science, Dr. H. Hoovey, who lives in the Eiffelberg Tower, played by Hans Conried.

In the live-action film How the Grinch Stole Christmas, there is a mayor named Augustus May Who, played by Jeffrey Tambor.

There are differences between Hoovey, May Who and McDodd that are instantly noticeable: Hoovey, similarly to Horton, wishes to reveal the existence of other worlds to his world's inhabitants, May Who is a pompous, arrogant man who views himself as the only person worth listening to, whereas McDodd is "devoted, and fair and a little bit odd".

In the 2018 CGI film The Grinch, Whoville's Mayor McGerkle, voiced by Angela Lansbury, oversees the town's tree-lighting ceremony.

In 2000 How the Grinch Stole Christmas was developed into a motion picture, which became the first Dr. Seuss story ever made into a featured film.

Additionally, Whoville was referred to as "Newville" in the 2022 horror film adaptation The Mean One, based on How the Grinch Stole Christmas!.
