According to the official Disney World website:
Figment’s Brush with the Masters Scavenger Hunt
Can you find Figment? Slip into sleuth mode while searching for clues that lead to the elusive little dragon—leave no painting in the World Showcase unturned!
No other details are available as of yet, but it appears that everyone’s favorite purple dragon will be hiding in art around World Showcase during the Epcot International Festival of the Arts.
It is unclear if this will be a paid hunt with pin prizes like the Remy Hide and Go Squeak at the Food and Wine Festival or a free event.
