1. They like to play!
A giant Pacific octopus' intelligence rivals that of a cat or dog. At any aquarium, you are likely to find a personalized "O.E" (Octopus Enrichment) program, which includes custom-made games specific to an octopus' personality. Common activities include: fetch (with a rubber cat toy soaked in fish chum), puzzles that release a tasty frozen squid and frozen fish pops for a hot summer day! Octopuses remember faces and will excitedly rise to the surface for play time.
