Diego has given up his true identity of being a tiger and a terrible predator. He found a real family in the form of a mammoth and a sloth. He really liked this company, but he was often annoyed by the appearance of new friends in big trouble. He tried to come to terms with common sense and did not offend the environment. They had fun and had fun in their new valley, because they had to leave their previous habitat because of the ice age. Now, trying to enjoy spending time together with friends, the main characters needed nothing but safety. However, the situation is radically changing, because the weather again does not give them a quiet life. It turned out that the guys would have a problem. The flood is moving due to warming. Now they have to think about how to protect the local inhabitants from death in the water.

There is practically nothing to build the Ark from, there are no improvised materials, and time is not on their side. The characters join forces and again go on a journey in search of a new home. But on the way they will learn a lot of interesting things. Including meeting a girlfriend for a mammoth. Previously, Manfred was completely alone, and believed that all the animals of his species had died. And now there is a chance to unite with this girl, and restore the fertility of the population. The situation is aggravated by the fact that she considers herself a possum.
