Name: Gary the arena

Levels: Two 15cm high raised platforms, one at each end, dimensions 2.5m x 15m, linked by 1 15cm high bridge down the centre 1.5 metres wide
Hazards: Entire arena except platforms is submerged in 10cm water, for extra annoyingness
Extra notes: Fully waterproof, arena material is very strong, not magnetic, and doesnt rust. OOTAs not possible.

...Mark, is this really necessary? Your reputations gone south as it is, and pointless threads like this wont help things.
