An octopus at the Blue Reef Aquarium, Newquay, has grown quite attached to a Mr Potato Head toy.
The 18-month-old Giant Pacific octopus, named Louis, was given the children s toy by the aquarium staff as part of an enrichment program, and it has since become a firm favourite.
Aquarium curator Matt Slater told BBC News that its bright colours, strange shape and moveable parts make it fascinating for Louis.
The enrichment program is designed to ensure that Louis, who well known for his curiosity and intelligence, gets the mental stimulation he needs within the aquarium. He has been at the Blue Reef Aquarium for nine months since arriving from Vancouver, and is currently 1.5metres from tip to tip.
The aquarium team have devised a number of toys and puzzles to enrich Louis life and keep him active, but none have proved as popular as Mr Potato Head, which is definitely his favourite at the moment.
The cephalopod can be found playing with the toy for an hour at a time, which contains the added bonus, or maybe more an incentive, of food.
The secret space within Mr Potato Head allows us to hide tasty treats like fresh crab inside, and that perhaps more than anything has resulted in him becoming such a hit, said Slater.
