Klonoa Heroes Unlockables, Easter Eggs and Secrets (GameBoy Advance)

Klonoa Heroes: Legend of the Star Medal is an action role-playing game developed and published by Namco and released in Japan in 2002. It is the first game in the Klonoa series to combine both standard action-gaming elements with CRPG features. Taking a unique twist on the normal gameplay of the Klonoa handheld games, Klonoa Heroes instead relies on the player moving Klonoa, Guntz, or Pango across the screen from a top-down perspective, having them defeat enemies and earn experience points in the form of Dream Shards (small, crystal-like objects) and gold, which is used for currency, along the way.

Klonoa once again utilizes his familiar weapon, the Wind Ring, but this time the "wind bullet" he can fire from it can be either blue or red. Guntz's handguns and Pango's bombs work the same way. Characters can acquire different weapons throughout the game. Likewise, each enemy in the game is given a color affinity of either blue or red and Klonoa (or the other characters) can deal more damage to them by attacking with the same color.

Secrets

Revival when Koed
After you lose all HP but before you get returned to the map, there's a short amount of time in which you can use an item. This is especially useful with healing items, as they act like an Angelic Ring and revive you.
