Ancient Ones

The Ancient Ones, or at least statues of their likeness, can be found in Gobi's Valley in Banjo-Kazooie. The first statue rises from the ground in between Jinxy and the nearest pyramid. Fly through the ring on its head using the Flight Pad on Jinxy's back to make the next Ancient One statue appear. Do the same for all four statues to be rewarded with a Jiggy.

They appear to be pranksters or something of that sort. This is shown as when the player goes through the first ring they say that flying through all of the rings will defeat Gruntilda. After Banjo does so they admit that they were kidding and give him the Jiggy.
