WarioWare Gold
All of the components.

The Unknown Components are souvenirs from WarioWare Gold that do not do anything in particular until all ten of them are obtained. When all ten of them are obtained, the Love Tester 2.0 is unlocked. Each component is either shaped like a heart or has a heart icon on them.

Each Unknown Component has the exact same description: "A fragment of something that somehow reminds you of your quest for love... (Collect 10 components to unlock something special.)"
