Tamagotchi

Remember the Tamagotchi? That beeping keychain that demanded more attention than a middle school crush? It's battling it out in the 'Greatest 90s School Essentials of All Time' league. Imagine trying to keep this pixel pet alive between math problems and lunch breaks. It was like a crash course in responsibility with a side of panic whenever it started beeping during a test. And now, it's a contender here, making us all nostalgic and defensive over our digital parenting skills. You can't help but root for it—it's the underdog with a resurrection story!
