What is “centrifugal bumble puppy”? why is it important for games to require a complicated apparatus?

A game in which children throw a ball onto a rotating disk that throws the ball back in a random direction and is meant to be caught.
Certifugal Bumble Puppy is played with a bunch of kids and they throw a ball on top of a steel tower, and the ball rolls into the interior, and falls onto a rapid revolving disk and is hurled to someone who has to catch it. The purpose of games is to recquire something that needs to be bought in order to increase consumption. In this case, machinery is needed for the game.

I'm guessing a 'fragment'. read over the sentence and question again before you move on.
