Level 58: King of the Mountain
Follow through the level and after the annoying bumpers you´ll reach a checkpoint. Go up the ledges and past the two fans and you´ll find a gyrocopter. Wait for another gyrocopter to spawn, then activate yours and grab the one that respawned, then jump up the wall in front of you. You´ll literally find a whole new path around the mountain. After you jump up the wall you´ll land on a yellow ramp. Continue forward and you´ll see a ledge that you can drop down to. Follow it around, jump the gap, and on the right side you´ll see a veeeeeery thin path along the side of the mountain for you to walk across. Go all the way across it, past the corner, and when you hit the wall, face the wall that you´ve been hugging, then with your blast at full, activate the gyrocopter and jump blast up the wall, bouncing into the wall to give you extra height, and the egg will be on top of the mountain.
Level 59: Natural Selection
Go through the level, and when you get to the part where the platform has just came up through a hold as you went up numerous ramps, and then you choose to take two paths as the platform is about to go into the small gap
in the wall (you´ll be at about 1 minute if you started on the moving platform around 4 seconds), take the left path, and when you get to the top platform you´ll find a gyrocopter. Get the gyrocopter and wait for another one to spawn. When it does, activate your gyrocopter, grab the one that just spawned, and jump up to the level right above you. Look in front of you and see the very tall pillar? The egg´s on top of it. Go forward and on the right side CAREFULLY drop down onto the level below, and on the bottom part you´ll see the super jump powerup. Activate the gyrocopter, grab the super jump powerup and then super jump up to the top of the pillar to get the egg.
