Devilgotchi

Also called Debiru no Tamagotchi in Japan. This is a version of tamagotchi in which you raise a little devil and have to keep it under control. One does this by disciplining it when it plays tricks on you like leaving the screen or calling for your attention when it does not need it.

Some of the characters are the same as other versions but have black wings making them into devils. In this growth chart the red arrow appears to indicate that under certain circumstances one can get a secret character. This tamagotchi is unusual because it does not have a clear baby stage.
