The Jungle Bat is a common type of bat found only in the Jungle and less commonly in the Underground Jungle. They can easily overpower any unprepared player, so exercise caution when entering the Jungle. In Expert Mode, they gain more power and can inflict the Feral Bitedebuff, making them a very obvious threat. Like most other bats, they cannot enter Water.
Jungle Bats, as well as Cave Bats, Hellbats, and Spore Bats have an unused frame in the animation that seems to depict a Jungle Bat hanging upside down. This may mean that bats were originally planned to be able to hang on ceilings but was later decided against.
If the player is becoming overwhelmed by groups of Jungle Bats, one thing they can do is hide in pools of water, as the Jungle contains plenty of it. The bats will try to enter the water, yet won't be able to. The player may also want to use a Breathing Reed to prevent themselves from drowning.
The Bestiary entry for the Jungle Bat: "These small, annoying creatures aren't to be underestimated. A deadly end awaits for those swarmed by these fangy rodents."
