Linux Games: Fillets-NG

Fish Fillets Next Generation is a Linux port and rewrite of a game originally called (simply) Fish Fillets. The game starts with our friendly fish protagonists sitting aroung the table discussing whatever it is fish discuss, when suddenly, a heavy metal cylinder drops on the table in front of them ... a talking cylinder no less. Something is obvioulsy afoot (or afin) in their world, and the intrepid duo decide to go out and investigate. There's only one problem — the cylinder has separated the pair and made it impossible for them to get out.

No, not impossible, just puzzling.
