The Star Wooparoo's

I have seen many posts about how people got their star Wooparoo's.  I tried for Ray, but not sure how to go about it.  I noticed that my Light Temple is not lit up like everyone else's.  What can I do to make it look lit up?  Is there something that needs to be done other than summoning Ray with Pepe and Coraloo, or Leaffie and Dolley? Any help would be appreciated.
