Staff at the Santa Monica Pier Aquarium in California say the trickster who flooded their offices with sea water was armed. Eight-armed, to be exact.

They blame the soaking they discovered on February 24 on the aquarium's resident two-spotted octopus, a tiny female known for being curious and gregarious with visitors. The octopus apparently tugged on a valve and that allowed hundreds of gallons of water to overflow its tank.
