Walk on lava
Begin game play on "Blarg's Pit" (level 2-2) and reach the first heart. Jump.
Shrink in "Piranha Groove" (level 4-4). Hit an egg block while shrunk to create a very small egg. Take it while still shrunk. The egg will remain small as you return to normal size. Note: The mini-egg is still as powerful as the full-size version.
Collect six melons in a row during a mini-game to get a heart fruit. Eat the fruit to create a letter made from coins at the end of the mini-game. If you use the letters in the order of appearance by level, they spell the following phrase: "YOU ARE YOSHI'S GREAT PARTNER".

To get the Purple Yoshi, collect all of the heart coins in any level.
In the stage select screen, use the C buttons to change the camera angle or press R or Z to zoom in and out.
Melons from ? Boxes
Here's a crafty way to get melons. Find two ? Crates (Not floating boxes, the yellow, green and blue crates) that are near or next to each other. Now, Sniff-sniff to make sure both are empty. If one is full, break it. If neither are, push them up against each other for a while, and out pops two melons.
Eat Blocked-off Fruit
Can't get a fruit or other object because it's behind a wall? Here's what to do... simply shoot your tongue straight up or down, then rotate the analog stick toward the object. Your tongue should be fully extended and pass right through the wall!
Change Shy Guy Colors
To change the color of a Shy Guy, pound the ground next to it.
To break bubbles without using an egg, simply run into them repeatedly.
Black and White Forever
Beat the game with the Black or White Yoshi. When you start a new game you'll be offered the chance to play as Black or White Yoshi for the entire game.
Beat Baby Bowser
This is far too easy. The tree to the right of the screen is full of fruit. When you eat a piece it will grow back (around five times per piece.) It also has a heart fruit (invincibility) which will grow back twice. To start, Bowser will fly about on green ghosts. The easiest way to hit him is to get rid of all of your shells and grab a bomb with your tongue. Throw this and try to hit him with it. After hitting him three times the ghosts will disappear. (If you are injured at all, eat some fruit.) Now he'll jump around the screen. Once again throw bombs, remember that they rebound off walls unlike shells allowing backhits. Another three hits and you've won. Incidently if you have the black and white Yoshi's they'll be in the ending too.
Heart Fruit Tricks
If you think the only thing that the heart fruit does when you eat it is make you invincible temporarily, you are wrong. Here are some of the other things it can do:
1. It saves you a ton of eggs. If you pound the ground next to a fruit trapped in a bubble when you are invincible, the fruit will break open!
2. It makes your tongue much longer, helpful for getting enemies from a distance.
3. Lastly, if you pound the ground next to a shyguy while you are invincible, the shyguy will turn into fruit!
#1: Go to Bone Dragons Dungeon in Story mode (page 2, board 2.) Go most of the way through the board to the tulips. Go to the tulip to the left of Miss Warp. Stand in front of the tulip and eat it. Fire yourself upward and break out of the egg near the ceiling. Grab the black egg and complete the rest of the board as usual.
#2: Go to Page 2, Stage 4. When the level begins go up through a couple of rooms until you reach the room with the ghost snakes in it. Rapidly jump from snake to snake until you see a floating bubble. Pop this with an egg, grab the black egg and finish the level as usual to get Black Yoshi. This Yoshi is even better than white yoshi as he can eat anything including the black heios who carry the blocks on the final page.
#3: This one is found on page 2, level 1. Find the tulip that turns you into an egg and shoot yourself up. You will land on a platform with a bubble -- pop it and you get the black Yoshi egg. You will be able to select Black Yoshi once you finish the level. Note that you can only have ONE Black Yoshi at the time.
#4: Go to Page 2-3. Go through the level until you find a Help Box that tells you about a "big egg." From there, go to the left and jump on the last floating rock, then jump on the one above that, and shoot the "?" bubble with an egg. You will receive the black egg. Beat the level and you have the black Yoshi. Note that you can only have one black Yoshi at the time.
