==Description==
We can't stop here.
==Effects==
As the name of the stage implies, waves are comprised entirely of bat enemies, including many unique variants of Pipeestrello.
Enemy health multiplier increases by an additional +0.2 per minute and the enemy speed multiplier by an additional +0.025 per minute.
This stage has a -75% XP bonus, meaning the player actually collects less experience.
Orologion and Nduja Fritta Tanto cannot drop from light sources in this stage.
After collecting both Apoplexy and Chaos Malachite, three pressure plates labeled "A", "B" and "C" will appear on further visits to the stage, due north to starting area, marked as a "?" on the map. Stepping on them each toggles a background effect; This effect is only visual and has no impact on gameplay.
==Hyper Mode==
The hyper mode for this stage is unlocked by default after unlocking the stage.
Hyper mode in Bat Country has +80% Gold and +10% Luck bonuses.
==Items==

===Stage items===
A small circle of nine Gold Rings appears to the northeast of the starting area on further visits to the stage after collecting both Relics on this stage. Approaching them will cause 9 Sun Atlanteans to spawn.
The Yellow Sign has no effect on this stage.
===Relics===
Two relics are located in Bat Country. Each one of them appears at the center of a large square of Diamonds on a given time and disappears after one minute has passed. When they disappear or are picked up, they can continue to appear on the map and even move on it, even though they are no longer on the field.
* Apoplexy, which appears at minute 9:00.
* Chaos Malachite, which appears at minute 18:00.
==Waves==
Enemies in Bat Country approach from all four sides of the player.
