Holle Bolle Gijs first appeared at Efteling in 1959, designed in the fairytale style of Anton Pieck as talking bins that encouraged children to feed them paper instead of dropping it. The family grew to include themed versions around the park, including the Tyrolean dressed Tiroler Gijs, whose Alpine styling gives him a distinct yodelling character. Clips of their short calls and thanks have since circulated among Dutch fans online, shared as soundboard bites by visitors who grew up hearing them on every trip.
