Tuttle Twins Season 4 Episode 2 Melting Money & Fancy Fridges Episode Title: Melting Money & Fancy Fridges Episode Description: When the Tuttle family debates buying a fancy new fridge, Gabby takes the twins to meet John Maynard Keynes, who advocates for short-term thinking, and Saifedean Ammous, who advocates for long-term thinking instead. After Keynes' boat burns and capsizes, he unwittingly presses the "Food Me" button on Gabby's scooter, causing the twins to be transported into the Tuttles' current fridge, where sentient food items use ice cubes that have to be spent before they melt away. After unsuccessfully confronting the Federal Freezerve about his ice cube production, the twins later get the idea to use fruitcake as an alternative, hard-to-get currency that would not diminish in value like ice cubes.
