Otto the Troublemaking Octopus

Staff at an aquarium in Germany believe that an octopus called Otto had been annoyed by the bright light shining into his aquarium and had discovered he could short-circuit it by climbing onto the rim of his tank and squirting a jet of water in its direction.

Otto has been bored as the aquarium is closed for the winter, and is constantly craving attention while coming up with new stunts. Once staffers saw him juggling the hermit crabs in his tank, while another time he threw stones against the glass damaging it. And from time to time he completely re-arranges his tank to make it suit his own taste better to the distress of his fellow tank inhabitants.
