We've reported on some amazing LEGO sets this year. Products like the functional LEGO foosball table, the motorized LEGO lighthouse, and the crazy LEGO Bowser puppet are elaborate and groundbreaking---unfortunately, there's something we've overlooked. We missed the LEGO poop brick.

Back in May, LEGO announced a LEGO City Train Station. It includes an open-air train station, a shuttle, a railway, a tow truck, and a porta potty. At a glance, this is a pretty unassuming LEGO set.

But as Louie Mantia Jr noticed, LEGO's porta potty hides a special secret. And it's a big piece of poop. Screenshots of the set's instructions give us an up-close and personal look at the LEGO bowel movement. It's shaped like a big chocolate swirl, and it's about the size of a LEGO minifig's head.

The LEGO City Train Station is proof that minifigs go "number two." At least, that's what I thought at first. In a tweet responding to Louie Mantia Jr, someone noted that this LEGO poop isn't new. In fact, it was originally used to represent dog poop. (Maybe a dog used the porta potty?)

Clearly, we need to go deeper to solve the mystery of this turd. The BrickLink website reveals that the LEGO poop brick is included in a total of 59 sets. It regularly stands in for dessert toppers, bedpost accents, and other items that look similar to poop. It's also featured in LEGO's The Office set---that means it's technically a representation of Todd Packer's poop.

I'd also like to point out how, in official images, LEGO's porta potty is attached to a small hand car. It can go on rails. I'm not sure if this is a thing in real life, but it seems like a very cavalier way to handle a plastic box full of bodily fluids.

If you'd like to play with the LEGO poop, go ahead and purchase the LEGO City Train Station set. It costs $100 and includes 907 pieces. (For those who need the math, you're basically paying $100 for a LEGO poop and getting a cool 906-piece LEGO set for free.)
