If you cast your mind back to last week, you may remember that Rovio revealed its next Angry Birds Seasons update via a colourful photo on its official Twitter account.

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.
