Resident Evil 2 Remake (2019) - Keep Their Heads Ringin' Trophy Guide / Achievement Guide - Paralyze a licker's sense of hearing. [Bronze]

Simply throw a flash grenade at a licker.
For example, you will encounter a Licker in the corridor leading to the S.T.A.R.S. Office on the 2nd floor of the Police Station (and a flash grenade is inside the S.T.A.R.S. Office so it's a perfect opportunity to get this early on). Lickers are the enemies that crawl up walls and attack with sharp claws and whip around their long tongues.
