The coconut octopus crept closer and inspected the robot carefully. He touched it with one arm, then another, as if checking whether it was alive, rude, or useful. The robot did nothing. It did not steal his shell, chase him, or make any sudden moves. For a cautious coconut octopus, that was probably the best possible first impression.
Slowly, the octopus appeared to accept the new strange newcomer. The robot was calm, steady, and very good at staying quiet. That made it useful. The coconut octopus already had his shell for protection, but now he had something extra beside him: a strange, eight-armed object that might make his little home look harder to attack. In the ocean, sometimes good security is just looking more confusing than your enemy expects.
