Soap and Training Wheels had a double feature music video, same with Tag, You're It and Milk and Cookies. But the order of the songs are Soap, Training Wheels, Pity Party, Tag, You're It, Milk and Cookies and the other songs.
We all know Johnny and Cry Baby are the characters in Soap/Training Wheels music video. And at the start of the Pity Party music video, Cry Baby was writing invites for her friends, one of them being Johnny, we all know what happened at the same music video, alright. At the start of the Tag, You're It/Milk and Cookies music video, Cry Baby is seeing throwing party decorations in the trash, but what happened in the last song? Yeah... So Soap, Training Wheels, Pity Party, Tag, You're It and Milk and Cookies are connected to one another
