Mystery Pink Egg
To find the location of the mysterious Pink Egg from Banjo-Kazooie, go back to Spiral Mountain. Just above the tree stumps where the speed shoes are located is a hole. In the hole are metal bars enclosing in a Banjo-Kazooie Game Pak. To destroy the metal bars, you will have to learn about Grenade Eggs. Use them to blow up the bars. Go up to Gruntilda's Lair to find a Flight Pad so you can fly to the hole and break open the Game Pak to find the Pink Egg.

Mystery Blue Egg
Go back to Spiral Mountain and use the Flight Pad to fly up to a waterfall with a hole in it. Jump all the way through the rushing current to find the Game Pak. Use the Grip Grab skill to break open the bars.

Ice Key
The Ice Key from Banjo-Kazooie is hidden inside another Game Pak. You will have to learn the Grip Grab move to get it. Go to Jinjo Village, go behind the Green Jinjo's House, and find the sandy spot. You will see a crack in the wall. Go up on the platform near there to reach it and climb your way across to a hole. Be careful, because there are plants that will bite you. When you reach the cave, you will see the Game Pak.
