Can't say I'm a great octopus/mythical creature fan, but the water pump makes this one fun. The detail under the body is interesting. Will it adhere to a wall or desktop, Gary? If so, you could fill it with water and leave it about as a surprise.
I've seen the creature referred to on another board as a kraken which refers to a giant octopus like creature mentioned as early as the 12th century in Norwegian stories. The word "kraken" itself only appears in print in the 18th century. (According to an entry in Wikipedia, shortly to be amended(!), the kraken is based on the creature of the same type in Walt Disney's film Pirates of the Caribbean! Ye gods, how stupid can people be! Was there nothing before Walt Disney, the man who did most to destroy childhood?)
Oh, and many thanks, Gary, for this and the other pirate reviews.
