Make sure not to be holding X or Y when you jump on the P Switch, or you'll just pick it up and carry it around. Jump on the P Switch to make many coins appear, filling the room. Collect as many of the coins as you can before the P Switch effect runs out.

After the coins disappear, go to the right and go through the pipe.

Go to the right until you find a giant Yellow Switch. Jump on it and you will see an explanation of what it does. Press a button to complete the level. You will be asked whether or not to save the game. Now all the yellow Dotted Line Blocks throughout Dinosaur Land will now have Yellow Blocks in them. When you hit a Yellow Block, a Super Mushroom will come out.
