Black Yoshi
Level 2-1
When approaching Miss Warp 4 from right, go left, eat flower,
and shoot to the very top.
Level 2-3
Go through the level until finding the Help Box that offers
hints about a "big egg". Go to the left from this location
and jump on the last floating rock. Then, jump on the floating
rock above that, and shoot the "?" bubble with an egg
to receive the black egg. Complete the level for the black Yoshi.
Level 2-4
All the way to the right in the vine room.
White Yoshi
Egg 1
(Level 3-2) In leaf room, drop to bottom at the very beginning
for the egg.
Egg 2
(Level 3-3) After Miss Warp 3, go to the top vases. Enter
the tall red pipe to find it. Note: you must beat Cloudjin at
the end of the level without losing Yoshi.
Level 4-1: Shyguy
Go to the place where all of the Shyguys are on stilts.
There are four blue blocks there. Break through the top one on
the left and a Shyguy will appear.
Egg restore
If Yoshi is low on eggs, is not next to a egg block,
and super happy, prepare to fire an egg but cancel that action.
Yoshi will put the egg into the inventory and allowing it to be
kept.
Move fast
Unlock the Black Yoshi or White Yoshi by finding their
eggs. Then, use the Black or White Yoshi in a stage and get a
Super Happy Fruit. While Super Happy, Yoshi will be able to move
horizontally very fast during the Flutter Jump. This makes crossing
gaps a lot easier.
End the game with all Yoshis alive
Enter a level in story mode, then select a block 1-4.
As soon as you enter, turn it off then back on. Note: This might
not work with black or white Yoshis.
Snow
In the Poochy and Nippy stage, go to the location where
all of the birds with the bombs are found. Get seven melons or
get a heart and it will start snowing.
Melon instead of heart
If you eat only melons, at the end a melon will appear
instead of a heart.
Glitch: Falling cloud
Go to trial mode, then go to "Rail Lift".
Flip past the first two pages. When you are on the cloud, before
it goes back, walk off it. The cloud will fall.
