Kave Mart was a department store seen in the second season Dinosaurs episode "Refrigerator Day." A parody of Kmart, the store is visited by the Sinclairs, attempting to return their Refrigerator Day presents and thus buy a new refrigerator.

Salesmen Richard and Hank are baffled by the concept of bringing something back, but their boss realizes the advantages of a return policy. Out of gratitude, Kave Mart gave the Sinclairs their old refrigerator back and arranged for Earl Sinclair to get his Fridge Day bonus, on condition that the store control all rights and revenues related to the "return policy" concept."
