Unfortunately the help given in the game about the secret levels is not much use any more, but it was when I released this egg. It goes like this:
They all have one thing in common.
You will find it easier if you have the pre-release version.
The pre-release version of the game was the demo. It probably doesn't exist anymore on anybody's computers (it certainly isn't on mine) but basically it had two secret levels on it. Those levels can be found in the egg and are both in the second episode. This is what the secrets have in common. They are all in the second episode (yes, really!).
Anybody who knows their ducks from their onions will have probably realised that the green duck in this level has no purpose, because the seagull moves the orange ducks for you. But he does have a purpose. He is there to access the secret doorway. The secret doorway is in the tunnel above the rocket. Just move the green duck to the left hand side of the level then bridge up to the top. Walk right and he should soon enter it.
It is really easy in this secret level to earn big points. You get points by bouncing ducks off of your bat into the scenery. The bat follows the mouse so just keep clicking the use tool button (default: left) and adjust the position of the bat slightly to add more ducks and bounce them around. Simple.
Look at the bottom of the level. See the fan? There is an overhang to the left of it. The doorway is hiding under it. Just get down there safely (in other words don't fall too far) and the secret level is yours. You can forget about all those orange ducks. It doesn't matter if they die.
This secret level is truly original. The idea hasn't been replicated in any egg I have seen so far. You can ignore the message about Ducks version 1.2 at the beginning of it. I don't think anybody still has a version lower than that. In this level you get points for flicking switches and using balloons and bubbles. Start by turning your duck at the top of the screen into a leader. Move him left and drop him down onto the platform below. Turn him back into an orange duck and release a seagull. Let the duck enter most of the bubbles and then turn around and enter the rest. Hop into the first hot-air balloon, walk into the teleporter and enter the next balloon. Head left until you enter the next teleporter. Make sure that you land on the spring at the bottom of the drop and not in the balloon, otherwise you will die. When you reach the teleporter at the bottom, it will take you back to the top where you can now flick all of those switches to the right.
In the top-left hand corner of the level there is a rock. Teleport the leader onto it. The secret doorway is there.
Aliens will fall from the sky. Clicking on them will destroy them and earn you points. As long as there is one duck remaining you can still earn points so plan on protecting one duck. I advise choosing one of the ducks near a wall. That way aliens can only come from one direction.
Move your green duck right and build over any obstacles in your way. You will end up in the small hole to the left of the chain. Head towards the rocks to enter the secret level.
Ducks will fall from the sky. The rocket at the bottom will follow your mouse so use it to catch ducks. For some strange reason (I can't remember why) I made this level more than 1 screen wide, even though ducks only fall from the left-hand side. But that's not important. Look, just catch the ducks, OK?
As soon as the level starts, head towards the alien rather than away from it. You will enter the doorway before the alien gets you.
A really easy secret level. Collect all of the bottles at the top first, then drop down and collect all of the bottles on the middle floor, before collecting all the ones at the bottom. All you have to do is bridge over the glasses that get in your way. I told you it was easy.
