Winter Wonderham is the fifteenth episode in Angry Birds Seasons, the third episode celebrating Christmas, and the second episode of the Season 3 package. It was first revealed on the Game Center leaderboards, and was reported by Angry Birds Nest on November 19, 2012.

New features include Icicles and a new Ice Element coming from the ground. With this element in play, Birds that hit it will slide faster than rolling on normal ground. Sometimes, when hit, it's possible that Pigs and Obstacles, such as blocks, will slip and slide down, and the fortress will be easier to be unbalanced or collapsed.

Storyline
The following is from The World of Angry Birds Official Guide, as told by the Mighty Eagle: THE BIG FREEZE Winter seems to be coming around quicker every year. Twelve more months have passed and Smooth Cheeks still hasn't got the eggs. But he hasn't given up yet. His little elves have magicked the eggs away to a land of ice, snow, and giant candy canes.

Trivia

 * Winter Wonderham is the third Christmas-based episode in Seasons in three consecutive years. The other two are Season's Greedings for 2010 (Seasons 1) and Wreck the Halls for 2011 (Season 2).
 * This is the fourth episode having levels unlocked by advent-calendar, with the first being Season's Greedings (from Season 1), the second being Summer Pignic (also from Seasons 1), and the third being Wreck the Halls (Season 2).
 * In addition, this is also the first episode in Season 3 to have levels unlocked by advent-calendar.
 * Excluding the Season's Greedings animation, this is the very first time the Bad Piggies stole the Angry Birds' eggs during Christmas/a Christmas-based episode.
 * This episode contains 3 secret levels (4 for Android users, if you count the HP Intel Egg). One of them is a Big Red Bauble (name for Christmas Balls, AKA Spherical Christmas Ornaments) with star patterns on it. This is unlocked by earning 3 Stars on every level in the episode, like all Big Item golden eggs. The second golden egg can be found somewhere in level 1-18. The third Golden Egg was unlocked on Dec. 31 for the New Year's Eve of 2012. The last is a HP Intel Egg which unlocks 4 new Intel Christmas Levels. This level is exclusive to Android users.
 * The title Winter Wonderham is a corruption of the phrase and song "Winter Wonderland".
 * Level 4 is a special level based on Harbin City, China: the location of the Ice and Snow World Theme Park, which is the theme park that celebrates the Harbin International Ice and Snow Festival. This level will be in honor of the Angry Birds Seasons theme park in the Ice and Snow World Theme Park.
 * Level 4 is also the level shown on the screenshots on iTunes that has the ice fortress/castle in the background.
 * The app icons are now updated with the word "Seasons" on them.
 * When Bomb or Matilda's egg bombs explode, the background now shakes. (The screen will also shake when Bubbles balloons up) This also happens in the v.3.0.0 update in Angry Birds Classic.
 * When TNT Crates blow, they will also shake the screen. Again, this also happens in Classic now.
 * With this update, Bubbles stays inflated for a shorter amount of time, similar to Angry Birds Space. This also happens in the the v.3.0.0 update for Angry Birds Classic.
 * Like Haunted Hogs, when you fail a level, a different picture is shown, which is a normal pig eating a candy cane (similar to the episode button).
 * The Big Brother Bird, Black Bird and Orange Bird do not appear in the Intel Golden Egg levels.
 * The winnable item is a star-shaped cookie.
 * Like Piglantis, Hogs and Kisses, Year of the Dragon and Moon Festival, this was one of the episodes to have 2 different versions of the theme song. The other version of the theme song was heard during the Winter Tournament of Angry Birds Friends and on the PC version of Angry Birds Seasons.
 * It is also one of the two episodes to include four new levels upon the release of Power-ups in Angry Birds Seasons, with the other being Haunted Hogs. There are 3 levels to be unlocked by collecting a certain amount of stars, and 1 level for collecting 10 feathers by using Mighty Eagle. This feature was also used in Angry Birds Rio.
 * Before v.3.2.0, the background color was purple. But once the update came, the color changed to blue, changing parts of the environment. It was said that this was meant to happen to allow the blue color to bring the Aurora Borealis to life better than the purple one. Also, the mobile versions have a different version of the theme song, while the PC version has the original version.
 * If you have PC, make the screen small and wide and Harbin City will appear in the far left😃

Golden Eggs

 * On Level 18, a Golden Egg could be found. You must zoom out, and then use a Black Bird carefully to get the Golden Egg.
 * The 2013 Golden Egg was unlocked.
 * "The Big Ornament" can be unlocked after three-starring all levels.
 * Android Exclusive HP Intel egg that unlock 4 levels, earning by opening level 1-5 on an Android device.
