More Secret rooms:
     On  the  very  first  level,  in the first room, on the second of
those  two  platforms  which the bee circles, do the power stomp three
times

     On  (i  think  it's  level 1-3) Shouting Lava lava lava go around
those  big  stones  that  stick  up right out the ground (near the red
button)

     On be wheely careful on the first cog, when you look down off the
end  of  it  there should be a cream coloured platform, if you can get
onto this platform, there's a room there.

     I  snow  him  so  well,  inside the room with the buttons and the
penguins there are glimmering stars, walk into these.

     And on Licence to chill, if you stand in the middle of one of the
moving  wooden  platforms on the far side (away from the door) when it
disappears  at  the  end,  you  will  fall onto another cream coloured
platform
