He's not in the book, you know

It absolutely is. It's one of my favourites. I mean, I really like Winnie the Pooh, period, but yeah that was definitely one of the better ones.

(Not my all time favourite Pooh story, though. That'd be a toss up between either the Heffalump Movie or the Winnie the Pooh Musical - both really fun for little kids and with shockingly good morals for older viewers, the Heffalump Movie is an excellent story about not judging someone before you actually meet them that tackles prejudice really well for a kid show about a talking teddy bear, and the musical... Winnie the Pooh doing a Very Special Episode about authoritarianism, abuse of power, and positions of authority that don't need to exist is just so incongruous and out of left field, and yet they did it so goddamn well considering Pooh Bear's typical target audience. I like the Tigger Movie too because I really like Tigger, and Piglet's Big Movie has some of the best songs in the entire Pooh cinematic universe, but they're a far third and fourth to those two issue tackling and still utterly hilarious masterpieces.)

In some versions of the cartoon, they pull him out of Rabbit's door and he goes sailing into the air, only to then get stuck again in a beehive. Which is just so goddamn funny. I love it.

Cartoon logic. Pooh Bear does it less and lampshades it more than some older shows, but they do sometimes play it straight.
