A six-foot Giant Pacific octopus at Blue Reef Aquarium in Newquay, Cornwall loves his Mr Potato Head toy and "turns aggressive" when anyone tries to take it away from him.
'He's fascinated by it,' said Matt Slater, of the Blue Reef Aquarium in Newquay, Cornwall. 'He attacks the net we use to fish the toy out every time we try to take it away.'Mr Slater added: 'Octopuses are very intelligent and they like to be stimulated and busy.'
