Here's a more obscure secret that nobody will ever find unless they are good at glitches and sequence breaking.
In Banjo-Tooie, it is possible to get up the ledge that divide Jingo Village with the Wooded Hollow without the Grip Grab move.
The video below is a speed run that shows off a lot of glitches, including the one that lets you get up that ledge. Try skipping ahead to 3:22 to see the glitch.
If you attempt to do this skip without obtaining King Jingaling's Jiggy first, you'll be unable to simply walk out the door and the king has this to say.
"Yo there! I think you should come and pay me a visit before you leave."
Considering that nobody would ever be able to leave that way until they learn the Grip Grab in Mayhem Temple, I applaud the developers for thinking of everything.
