Exciting one last night, quite cinematic with a distinct Alien feel. I, along with several other people I don't know, were trapped on an oil rig that was under siege by a kraken. It's tentacles were incredibly long and seemed able to get to people anywhere on the rig to drag them off to that terrible snapping beak. It also had the unnerving ability to bite people in two, eat the legs and then insert a tentacle into the upper half of the dead body, using it as a kind of rudimentary hand-puppet to lure other victims to their doom.
In the end, we few survivors managed to kill the kraken by welding blades to the rig's main drill and "blending" it to death. It squealed horribly as it died and we all felt quite sorry for it - except for the Grizzled Character, who said it was probably calling for its (undoubtedly bigger) mother. Fortunately, the dream ended before she turned up.
