Rosie is Bee's best friend and a bit unstable, sometimes wondering if she is real or imaginary. She figures that since other people can see her too, she must be real! Rosie is the mischievous other half of Bee, often coming up with ideas for things to do that Bee probably wouldn't do on her own. Rosie likes rock and metal music and enjoys playing the drums because, as she says "I get to hit things and make loud sounds!". Her most favorite thing in the whole wide world are ICEE beverages. The Icee marketing really did a number on her!
