The polar bear mother has food in her mouth, and the two children are very clever to follow her, just waiting for her mother to give them food later.
Mother kept walking with food in her mouth, but she didn't give them anything to eat. The children were a little behind her.
Finally, when the two children couldn't walk, the polar bear mother actually ate food with her mouth, completely ignoring her children.
Mother polar bear has finished her food, but two little brown bears still haven't caught up. It turns out that it is selfish not to go into the water to feed your children!
