Yes, there is but you need to get the massive pearl
The Aqua-Grabber game is at the iceberg, click on the diving vehicle on the right side of the it.

Collect soda barrels then find the amethyst and take it into the net
the broken aqua grabber in the hidden lake
The rare treasure on aqua grabber is the black pearl on clam waters it is worth 50 coins. There you have it!
in a cave in soda seas level at the top there is a strange rock. Bump it with the aqua grabber and a worm will drop. :)
It all depends on your skill level, but for me, I would say either Catchin' Waves or Aqua Grabber.
Aqua grabber and fishing are good for getting coins in club penguin.
You go AROUND it :)
