Missingno. is a glitch Pokemon. If caught, it will cause some minor glitches in the graphics. It is pretty hard to catch, seeing at it exists only under certain conditions. And here they are:
1. Make sure your character's name is ASH.
(Added note: There are other names, but ASH is the easiest to remember for me.)
2. Go to Viridian City and talk to the old man near the top. He will ask if you're in a hurry. Say "no."
3. After you're done talking to the old man, fly to either Cinnabar Island または fuschia, フスキア, フクシア City right away. Don't do anything else until you're there.
4. If あなた flew to Cinnabar Island, Surf to the east coast. If あなた flew to fuschia, フスキア, フクシア City, Surf to the Seafoam Islands.
5. Once あなた get to the coast of Cinnabar, Surf along the coast. または if at the Seafoam Islands, Surf around the coast of the islands. Either way, あなた will eventually encounter the elusive Missingno.
Hope this helped!
