Hidden items
  When you get to the cloud maze look for the masks. Kill them both then go left
  to the water. Go to the dead end & press up to find one 1up !, M-bag, and one
  of those little bottles.
  On level 4, "Bubbly Clouds," in the stage where you float straight up to the
  door that leads to the fiery eyeball monster, locate the door. Above the door
  should be a crescent moon. Float to the tip of the moon and hold Up. This
  should take you to a place where you fall straight down. There will be 2,
  1ups, and 3 full health pieces. When you exit you will go to the monster, with
  full health, and 2 extra lives!

Fly through most of the first and second level
  In the first level (Green Greens), just inhale (press Up) and fly through the
  level. If you avoid obstacles, you won't get hit at all. This works for most
  of level 2, also.

Tips for boses
1. Green Greens. To defeat the boss suck up an apple and spit it back at the
   tree. But watch out for his smoke!
2. Castle LoLo. This boss is a very easy one! All you do is suck in a crate and
   spit it out at one of the guys. But be sure not to spit a crate at another
   crate or the boss could hit YOU!
3. Float Island. You will see a seashell before you go to the boss. Suck it up
   or jump on it. Then just hold the fire button in and keep shooting the boss.
   But look out for the cannon balls he shoots out!!
4. Bubbly Clouds. This boss you just grab a guy and shoot him out at the
   eyeball. This is similar to the boss in Level 2. But he has 2 defences: 1.
   When he swoops down jump over him. 2. Watch out for his lasers!!
5. Mt.DeDeDe. You first have to beat all the bosses again. Go in the door for
   one of the bosses. Then once you've beat all of them again fly up to
   Dr.DeDeDe's picture in the middle of the room. It then will warp you to a
   fighting ring. The way to destroy him is to suck up the stars he makes when
   he gets hurt. Then throw them back at him. He has many defences but I will
   tell you only 1, you can discover the rest. He may run at you and try to suck
   you up and then spit you out but to dodge that just float up so he can't get
   you.

  Fighting Wispy, the tree boss, avoid hitting his nose- you'll lose 2 pts.
  vitality.
  Vs. Dedede- only get stars when he jumps, not when he uses the hammer- you'll
  get smashed.
  Round 2 bosses Lololo and Lalala- take a box from one and hit the other- it's
  much safer.
