SpongeBob SquarePants S14E07 - Blood Is Thicker Than Grease

Plankton's parents come to town and start up the potato-based Spud Bucket restaurant right next to the Chum Bucket, overtaking it and the Krusty Krab. While Plankton attempts to sabotage the Spud Bucket, Mr. Krabs and SpongeBob watch and have a laugh as everything will eventually return to the status quo.
