The enigmatic Troll: no, not your garden-variety internet troublemaker, but the star of Nordic folklore. Originally portrayed in old Norse sagas as aesthetically challenged, intellectually underwhelming beings huddling in rocky family communes, these creatures later received a villainous upgrade in Scandinavian lore.

No longer content to lurk under the bridge, they became the heathens your Norse grandmother warned you about. Trolls have since lumbered their way into modern fantasy, from Tolkien's Middle-earth to the dice-rolling mayhem of D&D.

The 1950s saw these former cave-dwellers undergo a surprising transformation, reborn as fluffy, rainbow-hued icons, courtesy of the inexplicably popular Troll dolls. Fast forward to today, and these once-menacing monsters have become merchandising marvels, even inspiring a dreamworks movie franchise.
