Gibbering goldfish

S1, E11: Melvin is out fishing. He's in luck - he catches a goldfish. But when he lands it he can hardly believe his ears: the fish can talk. Its name is Joshua. And as everyone knows, if you throw a talking fish back in the water, it will grant your wish. Melvin takes the talking fish to Lapitch and Co while he decides what to wish for. Meanwhile, Elmer has told Dirty Rat about the fish and the free wish.
