Put the screen saver on and walk away. If you have the four pets thing where you can put 4
in your tank put prego, zorf, stinky, seymore in your tank (prego if you have piranna
things, zorf to feed the guppies, stinky to catch you shells, and seymore to slow the
shells down) thats what i do and I have 20,000 shells by morning! easy shells here u
