Bobobo-bo Bo-bobo (2005)

Season 1: Episode 40

Now that the brother Haou has become more powerful, Bo-bobo unleashes a special attack to bring him and his brothers down: a madcap roulette where any of them (or his allies) can be smashes, struck by ninjas, or...turned into shōjo characters! And when they're finally out of the way, there's still the matter of Halekulani, who shows off an impenetrable money field that can transform anyone struck into currency! (Bo-bobo and the others may rather spend it than fight it...)
