 CONT: The energy on Kevins Power Pad is the source of many errors.  In the first few episodes, extra care is taken in showing how much  energy he has remaining, and a green lit square vanishes when a  "unit" of power is used up, or so we are led to believe. In  subsequent episodes (in most cases), energy NEVER disappears from  the meter, yet he ends up running out of power despite this. Another  error stemming from this is in Metroid Sweet Metroid when Kevin goes  to use it to paint the wall. His power is dead, yet one unit APPEARS  on it when he uses it.
