It's pretty forgettable, to be honest, but the episodes aren't even four minutes long. I wouldn't rewatch it and I wouldn't recommend it, but it's just about silly enough to keep me going through twelve super-short episodes.
It's a plotless random gag series about an anti-cute internet mascot character called Wooser. He's a dog-sized yellow rabbit monster and his purpose in life is to be bad. His favourite word is "bribe", he has a thing for schoolgirls' uniforms and he's so lazy that he can't always be bothered to get off the sofa even to have fun. A typical Wooser quote might be "there's nothing like eating with someone else's money".
...and that's it. The series has no continuity, no fourth wall and no storyline. Stuff randomly happens, then it's the end. I wouldn't even call it funny. It's just odd. Meanwhile the art style is a bit like Hello Kitty, except for brief interludes when it's not. Occasionally there are flashes of normally drawn art, usually because Wooser's ogling a girl in a swimsuit. At other times it's like a 1980s computer game, which includes the opening theme song. (I rather like the closing theme, though.)
Wooser has four sort-of friends, but they think he's scum. They're schoolgirls and I think he lives at the house of one of them, which is certainly a bad mistake on their part.
It's surprisingly dark if you examine it carefully, although the utter lack of continuity or urgency means that it doesn't seem that way. No one cares about anything, up to and including the death of the lead character. (Wooser dies twice and on one of those occasions even gets a funeral, not counting his death in the opening titles for every episode. Don't worry; he's always fine again in a twinkling.) Stuff that happens in this series includes:
(a) Wooser getting attacked and chewed by a fang-toothed melon.
(b) a Satanic Black Mass turning Wooser into a grasshopper that decides to destroy the Earth.
(c) schoolgirls saying to each other, "Did you know bodies are buried under cherry trees?"
(d) a bloody sea urchin attack.
Sometimes it's surreal. Wooser might turn into Kaijuu-Wooser or Mecha-Wooser, Destroyer of Cities. The girls might then fight him as a giant robot, or perhaps as magical girls with transformation sequences. (There are also brief references to One Piece and Steins;Gate.) To be honest, though, since the whole show is basically a big non-sequiteur, only one of its surreal bits actually managed to be surreal for me. That's the scene where someone says "the sunflowers are laughing" and Wooser has a dark hallucinogenic nightmare interpretation of this.
Is it good? No. Is there any point in watching it? Not really. However it's faintly amusing in a low-grade deviant sort of way, like Garfield might have been had he been actually evil (but still really lazy) rather than just a bit of a git. There's no way I'd be investing real time in watching this show, but three minutes? Yeah, why not?
