There are 3 clues for the two secrets in this egg and can be found in the Read-Me! section of the egg. They go like this:
They are on adjacent levels.
One of them involves some skill in plummeting.
STOP!!!
These clues tell you that the secrets are in levels next to each other, one of them requires falling and one of them involves stop signs.
Take a look around the level. There is a platform to the left of the teleporters that is being blocked by a storm cloud. Head right and fall down onto the first platform below you to contain a switch. Flick it. Then place stop signs over the gap so that you can reach the platform. Before you fall off of the right hand side of the platform Count Duckula should enter the secret level.
It should be obvious from the start of the level that you have to detonate the saucer when he is at one of the bubbles to bring it down to the ducks. The only bubble that will put your duck into the tunnel on the right is the second from the left. When the duck enters the tunnel teleport the green duck on top of the tunnel and make him collect as many bottles as he can. To collect the rest, release a ghost next to the orange duck.
Start the level by quickly bouncing down to the bottom and into the teleporter. Your green duck will now be at the top of the level. You want to bring him down to the storm cloud near the alien as the secret is behind it. Just make sure that you don't flick any switches. The best way to do this is to stay as far over to the right as you can.
