This article is about something not canon to either the storyline of the TV show or The LEGO Movie franchise.
The Golden Pick Axe is a Skulkin weapon used by Bonezai. As the name suggests, it is a large pickaxe, identical to the Grim Pick Axe apart from it being a golden variant. According to its official description, it is made of solid gold and is highly desired (whether for its monetary value or its power in battle).
No matter who or what you are digging, the Golden Pickaxe makes a deep impression. Made of solid gold, it's really made for fighting... It has to be, everyone wants it.
