Angry Birds Seasons

Angry Birds Seasons (formerly Angry Birds Halloween) is the second game in the Angry Birds series, which contains episodes based around virtual-world holidays. It is available on all major platforms.

Seasons was initially released as Angry Birds Halloween on October 20, 2010. The name was changed in December to Angry Birds Seasons with the Christmas episode, Season's Greedings. Updates have continued since and are listed below.
