How get the highest score possible in a level:

To get the highest score possible in a level, here is
what you must do. First, pick Green Yoshi as your Yoshi
for that stage. Then, play through the level. Gather 
ALL the coins, egg, stomp, or eat ALL the bad guys, 
make sure to end the level having a FULL Flower Meter, 
and find and eat ALL 30 of the melons. Melons are worth
108 points each, and since they are also one of Green 
Yoshi's favorite foods, they are worth an extra 8 
(a total of 116 for just one melon!). The coins, 
enemies, and Full Flower Meter will give you the rest 
of the points. And that is how to get the highest score
possible. Good Luck!!! It is very hard to do on every 
level. Keep trying!
