Aqua Grabber Help?

[Maitias]

I have a question about Aqua Grabber, as you already know.

I got three achievements at Clam Waters.

Find the Main Treasure
Find the Rare Treasure
Finish Without losing a Sub


How long do I have to finish in for the Time Trial?

And how do I get the Compressed Air Sub?

When you`re in the big thingy which keeps the pearl and try to get it.It`ll make the "self-defense"reaction.Right there you must`n shoot in to the wall...

[Maitias]

I dont understand. I have to hit the wall?

Whats that for?

[Mr_Cash]

at the second level before u get the last tresure box u gotta hit the wall on the left side so a worm falls out.
use that worm to catch the fish and then catch the mullet.
