Mighty Beanz
Tiny weighted plastic beans with painted faces that flipped, wobbled, and raced down plastic tracks. "Play 'em, race 'em, collect 'em" — a pocketful of these got traded around every 2003 playground.
Mighty Beanz were created by the Australian company Moose Enterprises (now Moose Toys) of Melbourne, launching in Australia in early 2002 and reaching the United States in the summer of 2003. Each 'bean' was a small weighted plastic capsule decorated as a character — people, animals, monsters — with a hidden weight that made it flip, roll, and wobble.
The pitch was 'Play 'em, Race 'em, Collect 'em,' and kids did all three, racing the beans down plastic 'battle stage' tracks and trading them by the pocketful. The craze peaked in the US around the 2003 holiday season, and Mighty Beanz became the first Moose Enterprises toy line to break through to widespread American popularity.
The original run lasted through about 2006 before fading. Moose revived the line twice — around 2010–2012 and again in 2018–2019, the later wave adding tie-ins like Fortnite characters — but for millennials the beans belong to that early-2000s trading-and-racing moment.

Troll Dolls
Neon-haired, jewel-bellied good-luck trolls that clipped to pencils and crowded every desk and backpack. Invented by a Danish woodcutter in the 1950s, they rode a huge second wave of popularity in the early 1990s under names like Norfin.
Micro Machines
Thumbnail-sized cars, playsets, and whole cities scaled down to fit in your pocket — the whole appeal was how impossibly tiny and detailed they were. Sold by a pitchman who talked so fast you could barely keep up.
