Just an idea but what about a crab morph that you can also deal damage with
Like the crab battle bot event
Anyways, enough spammed for today, back on-topic:I think a surfboard would be pretty cool but there are already boats so they would need a pretty awesome animation. And, since the water is dead and doesn't have any waves and such, it might turn out to be lame. I think a Frisbee/Boomerang might be the better one.
A surfboard seems so much more useful to travel around the map because, non VIP players can't get speed boost in the water
