Cosmic Archive

The Cosmic Archive is a treasure found in Pikmin 2. It is actually a Famicom Disk System disk of the game . This treasure is found on sublevel 3 in the Hole of Beasts, and it is best to take out the fire geysers prior to retrieving it; alternately, Red Pikmin may be issued to carry it.

The writing on it is as follows:

ファミリーコンピュータ&trade;ディスクシステム

Which means "Family Computer Disk System", "The Mysterious Murasame Castle". The writing on the top is present for all Family Computer Disk System games.

Trivia

 * Interestingly, this treasure is not the only connection between Pikmin and Mysterious Murasame Castle. In WarioWare: D.I.Y., a microgame based on Mysterious Murasame Castle is present in the Japanese version, but has been replaced with a Pikmin microgame in the localized versions.
 * To a lesser degree, the Super Smash Bros. series combine elements from several universes, including Pikmin and Mysterious Murasame Castle. In Super Smash Bros. for Nintendo 3DS and Wii U, it is possible to, for instance, have Captain Olimar summon Takamaru as an Assist Trophy.
