One theory is that Inky slid across the aquarium floor – a journey of three or four meters – and then, sensing freedom was at hand, into a drainpipe that led directly to the sea. The drainpipe was 50 meters long and opened onto the waters of Hawke’s Bay, on the east coast of New Zealand’s North Island. Another possible escape route could have involved Inky squeezing into an open pipe at the top of his tank, which led under the floor to the drain. “When we came in the next morning and his tank was empty, I was really surprised,” said Yarrell, who has not launched a search for Inky. “The staff and I have been pretty sad. But then, this is Inky and he’s always been a bit of a surprise octopus.”
