There’s something special in your McDonald’s LEGO Batman Happy Meal: cheat codes! There are eight toys in the set and each one contains a stamped code on the bottom that unlocks something inside the game. LEGO Robin is happily gesturing to the undercarriage of LEGO Penguin’s sub. That little indented box between the wheels is where you’ll find the code.

I only have two of the toys, so I can only vouch for those, but people online have already sussed out all eight codes and posted alleged lists of the complete cheatiness. But get this, it looks like some toys may come stamped with different codes, meaning more than eight potential free unlockables.

From what I’ve seen, it’s nothing that you can’t unlock on your own. Using the Happy Meal codes simply saves you a ton of in-game currency. For the spoiler-sheepish, I’ll put the codes after the jump. And then it’s back to LEGO Batman, where I just used to create-a-fig machine to make a logo-less Green Lantern.
