Rare's famous N64 3D platformer, Banjo-Kazooie.
An early build featured in their "Rare Revealed" video series dating to when the game was still known as Banjo Kazoo shows differences from the released version. One example is the dance Banjo does upon collecting a Jiggy. It is longer and more exaggerated, and has a longer jingle to go with it. In addition:
• The early dance alters Banjo's position/rotation, so afterwards he has to snap back to face the camera.
• The Jiggy magically reappears in Banjo's hand after Kazooie (who at this point was still named Kazoo) swallows it.
• The Jiggy icon was originally a pre-rendered sprite with an image on one side of the Jiggy. In the final, it was replaced with a 3D model.
