Titre original : The Purple Panther - Part 1
Season 3‘s double feature! The LazyTown Kids want to learn more about the history of LazyTown and decide to open a museum.
As everyone gathers artifacts together, Stingy convinces Sportacus to loan his crystal, promising to be extra careful with it, so they will have something „priceless“ for the museum.
Robbie plots an elaborate scheme to steal the crystal right out from under the Kids‘ noses, to stop Sportacus from saving anyone ever again. Will the Kids be able to foil his plan and recover Sportacus‘s crystal?
