Hogs and Kisses

Hogs and Kisses is a Valentine's Day themed of Angry Birds episode, and as such, is available through Angry Birds Seasons. It was released on February 7, 2011. It contains eighteen levels, all set in a large plans filled with cherry blossom trees, raining down hearts. It introduces Cloud blocks, which act similarly to Snow blocks from Season's Greedings, as well as Pigs that wear bows. However, like with every accessory introduced in earlier additions, they can be knocked clean off: therefore, these bow-wearing pigs are not a new, separate species. There are new objects, which are chocolate hearts.

Unlike the previous episode, all 15 levels must be conquered in the order they are presented. However, the final three levels in this chapter cannot be opened by finishing the main levels. To unlock the sixteenth, seventeenth, and eighteenth levels, the player must "like" the app on Facebook. By simply pressing the large "like on Facebook" button on the second page and entering the site (even without internet access), these levels become available, and can be played, and completed, in any order the player desires. However, if you are going for three stars in all levels, these levels are a must.

There are two Golden Eggs in Hogs and Kisses, one which is collected on Theme V-7, and the other by getting all 54 stars.

Storyline
The following is from The World of Angry Birds Official Guide, as told by the Mighty Eagle:

LOVE BIRDS

Matilda is such an old romantic. Her heart leapt when she saw that someone had left her a box of chocolates beside the nest. She ripped open the ribbon with her beak and tucked in. Ugh! It wasn't chocolate — it was mud! Spluttering, she turned back to the nest to find that the pigs had once again made off with the eggs!
