Eep is a cavegirl (a Neanderthal) living with her family, the last one in the area. They're the last ones because they spend all their time in the safety of the cave. Due to the constant earthquakes and changing of the Earth's landscape, their cave is destroyed and they have to leave for the first time to find higher ground. Meanwhile, Eep meets a boy, who looks like a more modern human. He is full of ideas, like shoes and fire! He impresses her family, except the jealous dad, who up until now has protected the family.
All of the animals in this movie are animals that either never have existed, or could never exist, like giant flying turtles. One such animal is the big cute tiger with colors reminiscent of a macaw.
This is an animation the whole family can enjoy. It's funny and full of heart. I will give it a 7/10.
