What's the harm of Bump World?

Seeing the harm of the concave-convex world is easy to have sequelae.

For example:

When you see a roadblock stick, you can't help but say that you pick your head stick.

Seeing the mop reminds me of palos.

When you see a broom, you think of Paley, and when you see a dog, you run after it.

When it thunders, you will first think that the thunder lion is angry.

When you sit on the merry-go-round, you will think of Mi An Theseus, a knight without a horse.

Suitable for people:

Some details in the play should not be understood and noticed by children, so it is ok for them to treat it as a pure blood play.

Later, I thought about it. It may also be because the meaning expressed by Bump is actually profound. Perhaps the official thinks that children can't feel this profound meaning, which makes this animation lose its soul and is not suitable for children under 13.
