Actaually, Poke'freak, that glitch is well known. Sorry.
Mater spriter, yes, the unsafe missingno can be shiny. When I let my cousin borrow my lg he did all kinds of codes on it. In the box were all kinds of illegal ubers, a hacked shiny Mewtwo, and a shiny Nidorino. I took out the Nidorino, and sent it out, and it was a (?) that sparkled. I shut the game off quickly, and turned it back on. I left the Nidorino in the box this time, and ran outside into the grass, when up pops another missingno., so I decided to do a factory reset on it, and it was fine until I dropped it into a pot of hot water. Just ask Missingno. Master if you don't believe me.
