Forget the Cabbage Patch Kids, here's the coolest "birth" of a toy:
Each alien comes in a white egg, which is lodged in a clear plastic tube. Flushing the tube with water dissolves the egg in an exciting burst of fizz, revealing a weird little guy that looks either vaguely sinister or openly menacing, depending on whether he's in good or evil mode.
Once you fill the tube with a mixture of water and powdered food called "Sloog," you're officially the sole caretaker of an alien invader. That flashing light on its head is its heartbeat, powered by a lithium-ion battery that can't be replaced or recharged. Like every one of us, this creature is destined to die.
