The anime takes place on the screw-shaped island country of Nejigajima and follows the two "Bokyabots" Hebot and the Yurui Prince Nejiru as they collect different "Bokya Neji" screws. When the Bokyabots wear the Bokya Neji screws on their heads, they're able to compete in "Bokya Battles," battles for who can think up and tell the best jokes.
Lets get real here - this show is really good. Its a lot like Gintama in a few ways - meta humor (that manages not to be annoying) with constant character specific gags, reference humor without it feeling like a crutch and extremely esoteric humor. But the things that are so fucking INSANE about HEYBOT! are...high in number. I think the first would be how good the show looks. Or maybe it would be more accurate to say how much effort the team puts into stupid gimmicks. I'm not kidding when I say that this show is surprisingly well storyboarded and animated.
Second, HEYBOT! is
at times straight up nonsense. OK well its always nonsense, but sometimes the gags are so rapid-fire that they don't even bother to connect or make sense with anything. Its what I would call "stream of consciousness animation" where it feels like the animators are just doing whatever the fuck they want and slapping it together into an episode that is loosely connected and only held together by hopes and dreams. It feels like the people given key roles on the episode will just be given a summary of the episode plotline and then be sequestered to a locked prison cell where they will make the storyboards for the episodes without any communication with the rest of the team. Then they look at what they have and make some Frankenstein's Monster of an episode out of it.
HEYBOT! is like the ultimate evolution of anti-humor. Like an anime version of Tim and Eric. Jokes don't follow any real format. There can be a Die Hard quote in the pre-OP intro and then five minutes later they will finish the joke with Bruce Willis. HEYBOT! is a show for the Twitter memespamming age. Its a show made so that people can watch it on Twitter through me posting images of it on Twitter. Think about stuff like @dril and brain expanding memes - I used to find actual jokes with a setup and punchline funny or movies like Airplane, but now this is what I think is hilarious.
Third - and I think this is most important to its identity - HEYBOT! is a show made for no one but the people making it. HEYBOT! is a kids show, or at least its supposed to be. But it will have a reference from Super Street Fighter 2 Turbo. And its not just a simple reference to Street Fighter, its a direct reference to when Akuma comes in on the final stage and kills M. Bison to become the secret final boss. And its like a direct copy of the scene. And he does a Shun Goku Satsu. And the scene after has the not-Akuma doing his exact fighting stance. When HEYBOT! wants to make a reference, HEYBOT! doesn't half-ass it. Also SUPER STREET FIGHTER 2 TURBO CAME OUT IN 1994.
I can't really stress how completely out there the references this show throws out can be. Kids wouldn't know what the hell this is referencing. Hell, sometimes I'm surprised a Japanese person even knows what the fuck something is. Key example - Zardoz.
