Watch Invade All of the Humans

The general conceit of the series is that a couple of tiny, adorable robots are planning to conquer earth, but what they don't realize is that "earth" is a tiny patch of a dingy British park, in between a trashcan and a park bench. It's charming and weird and brilliantly stylized, using a combination of real locations, 3D and 2D animation, and manipulated images.
