How big is Gimpy? It's true that octopuses play games as stated in some books and some aquarium records. It all depends on their personality. It's so interesting and neat to have an octopus in captvitity thats friendly enough to play games or even play games with the pet owner. There intelligence is so high up there...that it makes them recognise intimacy with the pet owner and even friendship...or trust. That's one of the things I love about these animals.
