Kirby's Rainbow Resort -- Probably the longest running Kirby fansite on the web. Walkthroughs, art, forums, music, and tons of other miscellaneous Kirby content.
Official Kirby Super Star website! -- I'm amazed it's still intact.
Masked Knight
-- An interesting Meta Knight shrine and fansite where I pilfered the Official KSS website link.
Worth a look!
