Seasons: Back to School episode and new Pink Bird

Hi visitors. Today I've seen in the Angry Birds Facebook official page that Rovio will launch a new update to Seasons. This update will include a new episode called Back to School (we don't have to say why this name) and a new bird: the Pink Bird.
The Pink Bird will be first female bird playable in the Angry Birds saga, and its special effect is to launch bubbles to their enemies. I'm not sure how this effect will be used in the game. The episode and the new features will be launched very soon in the top mobile platforms (iOS and Android) and PC/Mac.
Here I leave the official trailer of the launch. Comment your opinion and see you later. Credits: Angry Birds Nation/Angry Birds official page (Facebook)
