Banjo-Kazooie Easter eggs

The Strange Door
On your way to your final battle with Grunty, go to the room where at the 'Game Over' Screen was at, next to the machines, there is a door with a knocker with a head shaped as a dragon. This same door was in the trailer for Banjo-Kazooie's BETA version of Grunty's Lair, The Giant's Lair.
