Secret Denjuu (Japanese: レア電獣, Rare Denjuu) are Denjuu that cannot be acquired through normal gameplay, only being obtainable by manually dialing their phone numbers. The phone numbers are not mentioned at all in the games and instead were released through various means such as the official Telefang websites, leaflets, comics, and tv commercials in Japan. Although the release of the secret phone numbers was originally spread out, they eventually all became available on the official Telefang 1 and Telefang 2 websites. In the bootleg version of the original game, dialing a secret Denjuu will cause the game to crash.
Secret Denjuu in Telefang 1
All of the secret phone numbers for the Denjuu are currently available on Smilesoft's official Telefang website, but were originally revealed through various promotions in the months following the game's release. All 14 numbers were later compiled in the final volume of the Telefang manga (published July 2001), and finally posted to the official website at some point in mid-2002.
