During the pandemic in Denmark, Danes were lured outdoors in an inventive way – by trolls. World-renowned recycle artist Thomas Dambo created 10 new sculptures around the country in a project he called The Great Troll Folk Fest (trolls were an apt subject for Dambo, who'd placed a series of "giants" around Copenhagen in 2016 and 2017). His goal was to encourage Danes to explore nature through a troll treasure hunt, complete with a troll map.
