The Cakeling was just a normal cake, left over from Story Mode's main event. But it was imprisoned by Victoria Von Bathysphere by being marked under a Skull and Bones jar. It broke out and landed on one of Victoria's experiments: a Brain Crane with twice the power. It captured Victoria and Monty's Sackbot son and took control of Victoria's House That Science Built. It then went on to capture a group of rebelious Sackbots to show them what it is like to be baked and wait to be eaten. Sack Thing went to face the Cakeling and, using the power of the Glow Birds, knocked it into the oven, burning it to a crisp. In The End, the cake was eaten by Victoria and the Sackbots of the valley.
