There are 8.7 millions of animal species in the world. Cubs, through animation, tells the bedtime habits of some of the most loved and mysterious beings, letting children know that it's time to go to bed.
We see a river surrounded by damp vegetation at the end of the day. Two baby otters play with each other by diving in and out of the water; the mother otter floats nearby, watching them.
Two sperm whales play near the water's surface. They "draw" in the water using the tips of their fins, while showing off their large mouths, swallowing large amounts of water.
We see a tiny hedgehog coming out of the vegetation and discovering a cockroach. It gets startled by its presence and runs away.
