This is not about the artificial animal you might expect to see on HN, nevertheless it is a patent for "Toy figures with self-moving parts, with or without movement of the toy as a whole imitating natural actions, e.g. catching a mouse by a cat, the kicking of an animal". I found the aspect of putting insects inside of the figure to create movement of the limbs very interesting. The patent is actually expired if anyone wishes to work on it.
