Because [[Cinnabar Island]] has no wild Pokémon data but the potential for wild Pokémon to appear, and that wild Pokémon data is not formatted when entering a new area, any location that can be {{m|Fly|flown}} from can have its wild Pokémon available on the coast.

This includes the {{safari|Kanto}}, so players can encounter Safari Pokémon under normal battling circumstances. Since the old man only writes to the first eleven wild Pokémon addresses, it means that extra Pokémon may be accessible even if the player's name is eleven characters long (which is possible with preset names). This grass Pokémon data is mapped to three 'uncommon encounters' and two 'rare encounters'.

Due to being able to find Pokémon over level 100, it is possible to trigger glitches relating to Pokémon with levels that are too high. If Pokémon over level 100 receives experience by battle, it will automatically go to level 100; Rare Candies will level up the Pokémon normally. If the Pokémon's remaining HP is already low, dropping to level 100 can cause the HP to drop to negative number, but it will be interpreted as a very high number, similarly to the [[Pomeg glitch]]. In {{eng|Pokémon Stadium}}, HP is shown as the actual amount; in [[Pokémon Stadium 2]], it will act as if its HP was full.

Reportedly, the first coast exploit discovered involved performing an in-game trade with an NPC and surfing on the coast.<ref>[http://www.gamefaqs.com/gameboy/367023-pokemon-red-version/faqs/38434 Okk's MissingNo. guide]</ref> This results in five level 80 hex:50 MissingNo. because the encounters are affected by the trade Pokémon's [[Original Trainer|OT]] name. Specifically, grass data is overwritten with "5D 50 50 50 50 50 50 50 50 50 50". The 5D byte is a control character that prints "TRAINER" and the rest of the bytes are 'end name' characters.
