An optional quest available in act one called Plunder Cove is full of references to the 1985 film 'The Goonies'. Hidden randomly within the level is a lootable corpse named Chester Copperpot, after the ill-fated Oregonian whose skeletal remains were stumbled upon in the tunnels beneath the Fratelli hideout. The boss of this quest, One-Eyed Willy, is also a nod to the film. The cove where you can find his ship also bears many resemblances to the location in the film. You can also find two socketables in this stage; Copperpot always drops a rare called 'One-Eyed Willy's Other Eye', and Willy himself has a chance to drop a unique called 'One-Eyed Willy's Eye'.
