A block of ice is an item found in Freddi Fish 4: The Case of the Hogfish Rustlers of Briny Gulch. It was mentioned by Sahara Slim when he told Goby and Moray to keep the hogfish on ice until he returns. Goby and Moray didn't quite understand the message so they thought he wanted to put ice in where the hogfish are being held, which they literally did. But Sahara Slim reveals to them that it was only an expression, meaning to keep them locked up, much to Goby and Moray's dismay. The block of ice is one of the clues to see if Sahara Slim is Mr. Big and the mastermind behind the rustling.
