(↑ Back to the ItemDex index.)
(hex:89) is a glitch item in Pokémon Yellow. It is an unterminated name glitch item.
When used with a 0x50 sub-tile early in the saved screen data, it will function exactly like the Pokédex glitch item. However, it will normally just freeze the game in battle without the proper screen data.
