Today, the Finnish developer has tweeted a Vine video (made with plush toys) in which it teases one of the forthcoming update's new gameplay mechanics: portals.
In this 6-second looping Vine clip, a Red Bird is shown entering one portal and exiting a connected portal, narrowly missing one of Rovio's infamous swine antagonists along the way.
Nudge nudge, kill kill
We sincerely hope you'll be able to nudge obstacles and pieces of scenery - not just birds - through portals, and use them as makeshift weapons to destroy any defences those pesky pigs may have erected.
Rovio is yet to confirm a release date for this Angry Birds Seasons update, but we'll let you know as soon as it does.
In the meantime, check out Rovio's Vine video for yourself below.
