When I was a child, my family bought me an assembled Transformers, which is made up of three animals: a lion, a tiger and an eagle, and can be deformed independently.

The gorilla took the little gorilla, put the little gorilla on the shore, then rowed over to pick up either the tiger or the lion, then came back with the little gorilla, then put the little gorilla on the shore and took the rest of the big animals. Finally, when you come back, just pick up the little orangutan. It's simple!
