Harry, a doctoral student in New Zealand, refers to his octopus as "evil." The octopus in question appears to share similar sentiments about his biologist. He says that, four months ago, he accidentally knocked over a pipe where she was hiding.
She can carry a grudge. The octopus sucks up water from a pump and spits it at Harry when he walks past. The video above is from one of her unsuccessful (but recorded) attempts. Harry has gotten thoroughly soaked.
