In the first Dr. Wily stage, after the check point there are six pipes. Two of 
them have weak respawning enemies. Use Jewel Satellite, and stand on top of the 
first set of pipes. You will occasionally get extra lives and a lot of Bolts. 
You can use this trick to replenish lives lost from the puzzle that is up the 
ladder. This also helps when completing challenges. Note: This requires a lot of 
time.
