As a preteen/early teen I was obsessed with the world of Mario
I was spending whole hours playing it. I even made a drawing presenting a bedroom furnished in the Mario style - a green pipe instead of the door etc. There must have been also a flower pot with the "power plant" from the game, picking which made Mario grow and another one with the "sundew" coming out of a pipe. I wish I didn't destroy it so many years ago. I was spending a lot of time looking at it.
In my imagination, Mario, Luigi, Princess Peach and all the other creatures we saw in the game (including the sundew, a goomba, lakitu and a cloud and so on) were kids, friends having various adventures in the Mario world.
