Dan and Ann are two child-like aliens from the faraway planet Band Land. Dan and Ann are brother and sister, twins, connected by a strong, flexible link called a Magic Band. Every Bandian shares this same form of physical bond with another Bandian. Bandians use their Magic Bands, which are flexible and can take on all manner of forms, to help them with their daily chores, much as we humans use tools. Dan and Ann's Magic Band comes in especially handy in this story. When Band Land's sun runs out of energy, Dan and Ann use their Magic Band to slingshot away from Band Land and come to Earth, in order to survive.—Anonymous
