An octupus found on the bottom of the ocean in Indonesia was concluded to have been playing too much Commander Keen Secret of the Oracle. Scientists arose at this conclusion when they saw it trying to mimick the behavior of the rock critters in the commander keen game. The below video highlights some of the copycat behaviors of the octopus.

Octopus are cephalopods and are known to be the most intelligent of invertebrates.
