Since everyone's saying "look it up" and posting memes rather than explaining anything, I will tell you confused children a tale passed down to me by a stranger on this world wide web.
(Though I'm verifying it myself as I type it. Research is important!)
"Winnie the Pooh's Home Run Derby" was a seemingly simple flash game released by the official Japanese Disney website in 2008, and an English translation released on the American Disney website later the same year. The game has Winnie the Pooh and pals playing a simplified game of baseball, Pooh as the batter and his friends as the pitchers, the goal being to hit home runs (i.e. just hitting really far). Each character uses more advanced and difficult throwing techniques than the last as you progress through the game. In theory, a fairly novel idea, but in practice, an absolute nightmare.
By 2012, a Japanese community had risen around the game because of how
insanely hard it was. The first few characters, Lumpy and Eeyore, require precise timing in order to hit the ball, but are pretty much what you'd expect from a kid's game. Then Piglet starts throwing curveballs, and already the learning curve has begun to rise. Then comes Kanga, and her pitches have already begun to break the laws of physics, bouncing up and down so that even if you're in front of it, you can do nothing but watch it fly over your bat.
Rabbit's pitches started out slow and deliberate, but then speed up and fly by faster than you can react. Owl's pitches zig-zagged side-to-side, causing more foul balls than a sports arena in the Wyrmwound. Tigger's balls actually
went invisible halfway through the pitch. You had to base all of these purely on skillful timing and positioning, and even then you might as well make a shrine to the luck god of your choosing, since a lifetime of religious service is faster than it takes to build these skills. Then there was Christopher Robin.
Christopher Robin, Pooh's dearest friend, was almost poetically parodic of the game. As the final character you could play against, he could use
any of the past characters' quirks at random. And he could combine them. You could be facing invisible curveballs or sped-up bouncers and you had no way of knowing what he'd do next. I don't recommend looking up the memes unless you have a high tolerance for slurs, because people went insane over these characters. There were Dante's Inferno parodies, "what's a god to a nonbeliever," anime screenshot redraws, and so on.
For your viewing pleasure, here are some of the less violent memes that still give you an idea of the insanity;
So, basically, a really weird official Winnie the Pooh game garnered a lot of attention for being the Dark Souls of stupid flash sports games based on Disney characters. I'm sorry for the long post, but this story needed to come to light.
