Timber Tumble is the twelfth episode of Angry Birds Rio and the fourth in the Rio 2 section, in the scene where the heroes defeat Big Boss and the loggers. But they don't appear as bosses or enemies and are replaced by Marmosets, who didn't appear in the movie either.
Hidden Harbor can be unlocked in this episode by finding a Golden Lock in level 14, which is hidden in a bush behind the slingshot.
- Various mechanical items appear such as machine parts, energy, and wheels.
- Blu receives a 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. The Call The Flock version of Blu can be used as a power-up in earlier levels, similar to Shockwave Bomb and Telebird.
