Here are some questions that either come up often, or that may come up often if they're not proactively asked and answered here. You can usually find the answers sprinkled throughout the guide, as well, but sometimes it's nice to have certain things all in one place. Note that there are mild spoilers.
Why do I need Sun Stones?
You collect the Sun Stones to gain access to boss battles at the end of each level map. Gather all of them within a level to gain access to an additional stage. Gather all of the Sun Stones from the standard and EX stages to acquire an additional Rare Keychain.
What are Keychains good for?
They look cool, and should be doubly interesting if you've been playing Kirby games for a long while, since they are modeled after characters that have appeared throughout the franchise's history.
How do I unlock the additional modes?
Clear the Story Mode and you'll unlock several additional modes and features. You can view any movies from the campaign in the Theater, battle in the Arena, or play Dededetour if you would like to play through the game as King Dedede.
