Timber Tumble is the twelfth episode of Angry Birds Rio and the fourth based on Rio 2, in the scene where the heroes defeat Big Boss and the loggers at the amazon. But they don't appear as bosses or enemies and are replaced by Marmosets, who didn't appear in the movie either.
The Hidden Harbor can be unlocked in this episode by finding a Golden Lock in level 14, which is hidden behind in a bush behind the slingshot.
In this episode, it contains various new features such as machine parts, energy, and wheels. But the best of them is Blu's new ability, Call The Flock, which when launched, he will call all the macaws and other birds and they will dive on the air, destroying structures and defeating marmosets if near.
