My entry is up... it gets 63 attacks in its full attack, has a move speed of 30 feet, and 6 hit-dice... and I am thinking that is exactly as it should be.
EDIT: Should probably change the type to Aberration... or MAYBE magical beast... Not that it will make much difference to its low hit-points for its damage potential... perhaps I should give it more HD...
EDIT^2: Making each level of interation 2 size classes smallerwould SHARPLY reduce the number of attacks you would have to roll (to only 7 I think) as well as being more mechanically/geometrically realistic... but I think that 3 levels of interation doesn't have nearly the cool factor of 6... maybe a lesser version and a greater?
