I’ve got a friend who has one of those Super Mario Sound Drop Key Chains. Press on the key chain and it will emit the same sound effect played when Mario is getting a 1UP.

While the Super Mario Sound Drop key chains have become rare commodities, Bandai is now making available sound drop key chain collections featuring the animes One Piece and Evangelion.

The One Piece 2 Sound Drops Gashapon consists of 6 different kinds of sound drops, each of them feature a different character and play a unique sound when press. Click here for purchase information.

On the other hand, the Neon Genesis Evangelion Sound Drops collection features 8 different key chains. And like the One Piece series, each key chain represents a character from the anime and plays a unique sound when pressed. Priced at USD 2.90 each, click here for purchase information.
