Okay, so I used to watch this movie all the time when I was younger. It was about two girls named Maria and Mirabella. They take this jourey into this garden type thing where they meet all kinds of creatures. I remember a song about glow worms being in there, and I remember them being in a cave at some point. They meet "father time" in the movie, and they end up getting caught in this place or something like that when the clock strikes a certain time. Maria, Mirabella and Father time were the only three real peopl in the movie. The rest was animated I'm pretty sure.
