Need Info: White Crab Sydney

A friend of mine has been offered these in Sydney (i'm in melb...) . i have checked pill reports and all crabs mentioned there seem to be shitty speed bombs, but nothing too recent. this is the description i was given :
"they are white, round in shape and a little domed ie not flat with a crab on the front, but mroe wavy like a scorpion crab with long front claws!"
they are only visiting and dont have access to a test kit....
thanks for the help....
ps ... what has happened to the melb pill reports thread?

bump - can anyone help?

ive generally found that all crabs are shitty
dont pay more then 20 bucks

the secret to success is clean underwear and a good top hat

thanks stylin - i think i will tell them to get spades or channels..... if they can...
