Go outside the museum level to the big statue. Walk behind it and it says " 02P " That means when you get your power level at 02, push the statue and you should fall into the secret level.
Get to the tree level in the park. When you get to the bottom of the slide on the floor there will be a "p08" sign on the floor (your as to be at 8 for this to work). And just jump on it.
Next, in the graveyard level go to the water and jump on the platform. When you get across there's a block with "p05" just push it and walk in the cave.
Then, in the factory level go straight when you get in the level. There's a
pipe with"p07" on it. Hit it and go in.
Lastly, go to the sea port level and go to the lifeboat and when the lifeboat goes down turn the camera in towards the wall and on the wall is "p09" whip it and you're in.
