Fight Safari Zone Pokémon trick

The Fight Safari Zone Pokémon trick is an officially-acknowledged glitch in Pokémon Red and Blue. It is performed by entering and exiting the Safari Zone, then going to Route 20 without traveling through any area that contains wild Pokémon on land, and finally Surfing along the east coast of any island on the route. This is most commonly done by Flying from Fuchsia City directly to Cinnabar Island, then Surfing on the island's east coastline which is considered part of Route 20. The glitch can also be performed using the east coast of the Seafoam Islands, as there are no land wild Pokémon on Route 19 in between.

When performed, the wild Pokémon that appear while Surfing will not be the usual water encounters for Route 20, but rather will be wild Pokémon from the Safari Zone area the player was most recently in. This glitch thus allows players to battle and catch normally Safari Zone-exclusive Pokémon as if they were regular wild Pokémon, bypassing the Safari Zone's mechanics, hence its name.

Cause

This section is incomplete. Please feel free to edit this section to add missing information and complete it. Reason: Specific explanation about 2x2 subtiles and how English R/B (but no other Gen I games) uses the bottom-left subtile for encounter tables but the bottom-right subtile to test if an encounter is allowed on that square. Link to explanation on Smogon forums. Explain how this leads to the Viridian Forest/Safari Zone encounters oversight where certain grass tiles will never give wild encounters (this oversight is currently undocumented on Bulbapedia). Only after all this, explain how the grass encounter table is not overwritten when entering an area that has no land wild Pokémon, and segue into how the Old man glitch works.

Extensions

The glitch is not exclusive to the Safari Zone, but can in fact be performed using any area. The wild Pokémon that appear on the east coast of Cinnabar Island and Seafoam Islands will simply be the wild Pokémon that appear in grass in the area the player was last in that has grass.
