HEYBOT!

The story is set on Nejigajima, a screw-shaped island nation, where two "BokyaBots" named Hebot and the Yurui Prince Nejiru search for special screws called "Bokya Neji." When the BokyaBots attach these screws to their heads, they can take part in "Bokya Battles"-competitions where the goal is to come up with and deliver the funniest jokes.
