If you are playing the original Gold game: You caught either a Missingno. (I'm pretty sure you didn't) or you caught the Red Gyarados. It's sad, but the Red Gyarados in Gold has a horrible glitch in it that has a chance of doing what you just described. If you are playing Heart Gold: I have no idea what happened.

There is no cheat code for finding missingno because missingno is a glitch, not a cheat.
