The name of this glitch item is taken from "ひんやりバッヂ" (CoolBadge); an unused Japanese string that was untranslated from Pokémon Red and Green, resulting in mojibake. ひんやりバッヂ is also the name of the hex:66 glitch item in Japanese versions.
Using this glitch item may freeze the game, both from in and outside of battle.
