Mabelina is Charlie's supposed crush. In Journey to the Center of the Dave, Max threathened to tell Charlie's crush on his blog if he didn't go inside Dave to get his iPad 360. However, when he mentioned this, Charlie denied that he had a crush at all. It is unknown if Max made the name up or if she is actually a person. Her only mentioning was in Another Oobi Vacation's Journey to the Center of the Dave.
