This movie i’m recalling is about this human like rocks or stone family which they also live like people and there is a scene where the baby wants to ride a bicycle so the stone parents made him or get him one. That’s all i can remember haha 😀 My sister said there is also a boy (a human) visiting them or friends with them. And i think they live in a cave or something like that. We’ve watched it when we were kids and i think it was 1996 to 2000. The movie is colored and i know we’ve watched it in VHS.
