Collecting Pokémon cards. Trading friendship bracelets. Painting your nails black. All these things have been trendy at some point, somewhere. But how did they become cool? And who made them popular?

Join Molly and co-host Harlynn as they explore the fussy and fabulous world of trends. Sanden will reveal how trends start and spread throughout a population—and why beige wallpaper it out and mocha mousse brown is IN! They’ll also learn about trends in animal populations like orca whales and chimpanzees. To top things off, Marc will start a fad by accident: fruit pants! (Yes, they’re literally pants with dried fruit stuck to them.) Plus, a super cool mystery sound.
