In blue: capturing Missingno, in my team(there was an empty slot when I caught it), then when I fought another Pokemon, the graphics were backwards. I mean, both my Pokemon and the wild Pokemon were facing the wrong way! And then when I attacked, the wild Pokemon's graphic picture thing broke up into little strips. I ran away, and the game didn't freeze up....
I totally cracked up when I saw that the battle graphics were backwards! But I got a little freaked out when the wild Pokemon broke up. That's never happened before....
But, the good thing is, I got a Haunter level 132, a Golduck level 145(now they're back at 100), and infinite Master Balls!
Now I know never to catch Missingno....
