This really is as terrifying as it sounds.
This is a puppet. It looks a bit like a penis.
It appears on a Japanese kids' show called Nihongo de Asobo, which means Let's Play in Japanese.
The show teaches children about tradiitonal Japanese culture.
This puppet features in an episode about "bunraku," which is a traditional form of Japanese puppet theatre.
One viewer tweeted these pictures of it, and got over 4,500 retweets.
They were tweeted by @xxxenxxx. The pictures have also been posted on 2ch, which is Japan's largest bulletin board.
