Play it out. Mario is a game where a plumber from New York visits a land of mushroom people who's princess is kidnapped by a dragon turtle, and he must eat mushrooms to get stronger and eat flowers to spit fireballs. In the most recent iteration, there are piranha plants that jump out of giant pipes, walk around, and do a whole song and dance number for you.

Clearly, there were a lot of drugs involved in its development.
