Rescue The Aquatic Animals

This forest is a place where you can see so many different types of animals, birds, plants, trees and everything else that you expect to see from a good natural environment. One of the biggest reasons for the fertility of this forest and for the many types of living beings here is the presence of the flowing stream. Today is one of the most forgettable days in the history of this forest. The flowing of the stream is obstructed by a huge piece of log and this has made life difficult for the aquatic animals. Can you restore the flow of the stream and save the poor animals?
