'Find the Panda’ With A Vengeance.

That’s right, we now have an unofficial trilogy of panda-related puzzles, and while we may be stretching it a tad with that title, it's certainly the most blockbuster yet. The Michael Bay of panda puzzles, if you will.

In case you're struggling to spot it, you're looking for the WWF logo (no, not the wrestling one, the cutesy animal charity one).

And if you just plain give up, we’ve included the reveal here - you big quitter.
