The bat is one of the enemies in Redungeon. The bat looks like a grey bat.
Unlike the slime the bat flies in circles. Even though the bat has a pattern it's very hard to dodge it. When you run into the bat with no protection three white scratch marks will appear on you and you die. You can kill the bat with Sir Gylbard's sword and shield or scare it away with Creep A. Crow. Duke Kazhan is immune to bats because he's a vampire.
