The key is community effort
I'll make it interesting, though. Unless you can provide your own pictures, tell us where the eggs are and I'll put the pics in here so we can all see. I'll replace my name with yours in the screenshot so you'll get all the credit for it. Level 1
: Do a boost jump to get on the bridge thingy.
Then just slide all the way down past the plank onto the next platform. There's your egg.Level 9
: Use the gyrocopter to get to the second platform. Turn to face the left of the bottom of the platform and you'll see a little entrance. Jump off and use the gyrocopter to glide in there.
Smooth sailing from here:Level 21
: This one's a little tricky. You can see the egg near the beginning of the level.
Get the Super Jump just after the first checkpoint. Go back down, and position your marble at this corner so you can roll off of it.
Jump off and guide your marble toward the egg. Use the Super Jump as your fall speed increases so you can better guide your marble to the egg. It'll give you the "Out of Bounds" message, but you'll get the egg. Level 32
: Get to where the trap doors are. You'll have to fall through this one for your egg.Level 44
: This one is directly below the exit. Make sure you have a Super Jump. Get to the platform where the exit is. Roll off the ledge just slightly. As soon as you begin falling, push your marble so that you're directly below the exit. As soon as you're lined up under the exit, use your Super Jump. You'll fall, but you'll get the egg.
