Looking for a movie I watched as a kid. Only have vague memories, I've asked everyone I know about it and no-one remembers it. What I remember is: 2 kids find a hole in a tree trunk, they go down it and find another land. In the "city" of this land there is an evil witch who has a magic peach (or maybe apricot?) tree. Eating the fruit from the tree will let them go home, but if the fruit hits the ground it pops like a bubble. Does anyone know this movie?
