Found this video of Jagex demonstrating there software and backend technology.
Any idea of what the two monsters in the video are?

Interesting.

Odd.

Saw this awhile ago, when I looked up "Water Troll" on RuneScape Wikia.

You found it, huh?
Look at who put the video up, 'Idesty' = Max.

I kinda figured it was Max, (the user's avatar) but I didn't see any post on the MSW forums about it so I put it up.
sorry if its already up.

And yes it is old, I got to it from a user on the forums stating something about this vid, followed by another saying it was a few months old and already found.

Indeed. These Water Trolls look rather interesting too....
