He's goading you.

Angry Birds creator Rovio has cheekily revealed that the forthcoming Angry Birds Trilogy contains an achievement that is expected to take around 300 hours to unlock.

The achievement is to clear all 700 stages with 100% destruction using the 'Mighty Eagle' bird.

Speaking to Digital Spy, executive producer Kalle Kaivola gleefully added:

I'd love to meet the guy who does that first, I'm just totally going to congratulate them.

Got 300 hours spare?
