Anyone else know about this? From Mario Wiki:
Have to say, I didn't. Interesting to know that the Wario Land/Metroid connection predates the one between Wario Land 4 and Metroid Fusion!
This game borrows some sound effects used in Metroid II: Return of Samus, another Nintendo game, also for the Game Boy. One example is when a boss is hit; the noise is the same one made when a Metroid gets hit. Other borrowed sound effects are when the player pauses the game and the sound of triggering mines which is the same as Samus going into morph ball. Both games were developed by Nintendo R&D1.
