(hex:95) is a glitch item in Pokémon Red and Blue.
Using this glitch item from both outside of and within battle will throw some bait, like in the Safari Zone. This includes halving the foe's catch rate constant.
If on the 'overworld' (02) sound bank, it will also play an isolated channel of a tune (possibly the 'follow me' theme). If used on the 'dungeon' (1F) sound bank it will instead play an isolated channel of the title screen music.
These effects are shared with BoulderBadge (glitch item).
