Staff at the National Aquarium of New Zealand found Inky missing from his tank one morning this week. They speculate that the octopus made a break for it in the middle of the night by climbing out of his tank (the lid had been left slightly open by mistake), sliding across the floor and then making his way down a drainpipe that leads directly to the ocean, the Guardian reports.
"When we came in the next morning and his tank was empty, I was really surprised," Rob Yarrell, a manager at the aquarium, told the Guardian. "The staff and I have been pretty sad. But then, this is Inky, and he's always been a bit of a surprise octopus." He also described Inky as a very intelligent animal.
"Octopuses are famous escape artists," Yarrell told the Guardian. "But Inky really tested the waters here. I don't think he was unhappy with us, or lonely, as octopus are solitary creatures. But he is such a curious boy. He would want to know what's happening on the outside. That's just his personality."
