I might be wrong here but i take it that very few people have ever heard of octopush. To cut a long explanation short it is basically underwater hockey, played on the bottom of a 2m deep swimming pool. You try to flick a 3kg puck around your team using a stick that is about 10" long.
Rather than me rattling on for ages you could get a better idea of what the sport is about if you search for 'octopush' elsewhere on the internet.
Anyway you're probably confused or bored by now but if anyone plays, has played, or would like to play, then please contact me.
Thanks
