The Grinch is one of the most iconic Dr. Seuss characters besides The Cat In The Hat. Many of Dr. Suess's stories have been adapted over the years into movies or television specials. The top characters to have their stories adapted in these forms are Horton from Horton Hears a Who, The Grinch, The Cat and The Hat, and The Lorax. The only Dr. Seuss stories to be adapted into live actions are The Cat and The Hat and The Grinch who surprisingly interact in a television special from the 70s.
I didn't find any of this out until I started searching for the Grinch's Halloween Special after seeing an article floating through my facebook notifications.

Shortly after finding the Halloween Special I discovered The Grinch and The Cat in The Hat crossover.

The specials were award-winning in their time and touch on a wide array of moral and ethical issues as Dr. Seuss always does. In the grand scheme of things these episodes make it even clearer how all the stories Dr. Seuss wrote could be considered interactions between multiple worlds, The Whos living on the speck with the Grinch and I guess the Cat and the Hat, then Horton's world of animals. I wonder then if The Cat in The Hat in the Hat is an example of a Seussian Multiverse because in the book The Cat in The Hat he interacts with two supposedly human children and a talking fish.
The reason why I think the children in The Cat In The Hat would have to be or most likely be human is that they don't have the same character design as The Whos and they do not have the same naming conventions of putting Who in front of everything. This evidence is probably extremely shakey and I haven't had time to see if there is already a Seussian multiverse theory. All of this just me pondering during the craziness of finals. Perhaps it is just the lack of sleep but for whatever reason, this topic is extremely amusing.
