Not sure it needs an sblock, as it was intended to be overt humor instead of covert, but the Giant has a habit of occassionally being too subtle for his own good.
[sblock]The mountain is the shape of Banjo's hat. It has two caves, in the same place as the markings on Banjo's hat. The trees at the base of the mountain are the color of Banjo's hair. The blue of the sea is the color of his coat, the three reefs are an off-blue that matches the three buttons on said coat. It's really obvious if you look at the orc "cleric" in the panel above the image of the island.
Essentially, the orcs have taken to worshipping Banjo because they see him as the avatar of their homeland.[/sblock]
