Lollipop Girl

Adventure Time debut (credit goes to You guessed it, Adventure Time Wikia). Because it's the 1st episode of Adventure Time in 2010, Lollipop Girl's skirt is wrongly colored

Lollipop Girl appeared in 2 shows, Adventure Time (which is good) and World of Jake (first!). She debuted in World of Jake's Christmas episode (Like Billy Trainers, she was not mentioned). She was then mentioned in the next episode Vase Breaker but she had wrong vocial cords (Microsoft Mary because the creator didn't know about VoiceForge). In the next episode the creator got it right in the early Birthday episode (VoiceForge ShyGirl because that sounds cute).
