Felek and Tola save the forest

Living in a clearing, Beaver finishes work on his life's work — a large dam in the middle of the forest. To create it, he cut down many trees and blocked local streams. The water poured out very quickly and a lake was formed in the middle of the forest, thereby drowning the cottages of Felek, Tola and their friends. Worse, it turned out that at night the water took away their neighbor Henia! There is no time to lose - friends come to the rescue! When they get to Beaver's house, they try to explain to him that building a dam in this place was a bad idea. Will they be able to convince the Beaver and save the forest?
