Way Cool With All Dragon Coins - Super Mario World 100% Walkthrough 

There are 8 dragon coins in total, it is possible, but difficult to get them all.
You'll need to bring a Yoshi into the level (any color will do).
When going for the 4th Coin, you'll need to be careful as sometimes the Fuzzies/platforms disappear. This can be seen in the video as when I try to go back after grabbing the coin, but there is no Fuzzy to jump on (it disappeared). I return to the right a little to make that left area go off screen and when I try to get left again a Fuzzy and a platform appear.
Coin #1 (0:00) - Hit the first switch so that it is off.
Coin #2 (0:24) - Under the yellow pipe.
Coin #3 (0:34) - At the end of the platform track
Coin #4 (0:40) - After the wings block. See above note.
Coin #5-7 (0:59) - In the Yoshi flying area.
