Ever wonder how those funky Android statues are made? A new video from the Nat and Lo project has the skinny on how the “tasty treat” naming scheme began in the first place, and what it takes to build a super-sized Android figurine. Hint: you need a mad scientist lab in New Jersey, which is where all of the statues have been made since the beginning.

Known in Mountain View as Android lawn sculptures, the statues represent the newest release of Google’s mobile OS, which this year happens to be Marshmallow. Each sculpture is cut from a large block of styrofoam, and then sanded and shaped to mimic the curvaceous contours of Android figurines. The guy who heads up the sculptures in named Gio, and he explains in the video above that styrofoam is actually the perfect material to work with.

Once the statues are finished, they’re shipped across country to Google, where workers and visitors can take pictures and post them to Google+. It’s a pretty complex and arduous enterprise, but it’s become a part of the Google culture—something the search giant says it likes to have fun with.

For example, one developer on the Android team said they purposely teased Milkshake at its I/O conference earlier this year to throw people off the scent of Marshmallow. If we can’t trust Google, who can we trust?
