UPDATE

Superkidz videos have been pulled from the Youtube Kids app. I do not know if this is permanent or temporary as I have not heard anything from youtube on the matter but as for now the videos are gone from the Youtube Kids app. However, the videos are still up on the regular Youtube site and are still suggested videos when your children are looking through kids videos. Please be aware of this when you are letting your children play on your phone or your tablets. Your children don't have to specifically look for these videos, with over 4,000,000 views, these videos will pop up as suggested videos.
