YMMV / Goosebumps (1995) S3E15 "Awesome Ants"

• Nightmare Fuel: This episode has one of the eeriest Downer Endings in the series just for the sheer implications for humanity. As if increasingly massive ants trying to attack you wasn't bad enough, Dave wakes up to find his family only has strange blue marbles in the fridge. He soon remembers that ants are actually skyscraper-sized, hyperintelligent creatures who herd humans for their own entertainment. The entire town is just one big vivarium with every human fighting over scraps of the blue food they are forced to survive on. After a brief chat with Mr. Lantz about his role-reversal Tragic Dream, Mr. Lantz solemnly tells the boy to gather some food for his family before it's all gone.
