Please take a look at this clip. I strongly recommend you watch it until the very end. The baby and the cat seems like they became a part of the Rube Goldberg machine.
What the baby and the cat is so hooked up on is a children’s program in Japan called “Pythagora Switch”. In this program many Rube Goldberg machine are introduced and there are many adult fans as well as children fans. Thanks to this program, in Japan, Rube Goldberg machine are called “Pythagora Machine” (or sometimes even “Pythagora Switch” like the name of the show). If you look up “Pythagora Switch” on YouTube, there are many clips about Rube Goldberg machine.
