The Bar is a meter placed on the bottom of the screen. Currently, there are 2 bars: the Water Bar which indicates how much water the player has (normal bar), and the Air Bar that indicates how much Air the player has while they are underwater (shown while diving, replacing the Water Bar).
The Water Bar and Air Bar will continuously decrease until they run out. Every animal can dive for a specific time, which opens up the air bar. When the air bar runs out, the player will be forced to resurface. Every animal also has a specific water decrease rate. When the water bar drops to zero, the animal will start to getting hurt (20% health of 100% every second) before dying of dehydration.
Bars, when it's value is 1/4, will start alarming the player by fading and its title will change to "LOW AIR/WATER" and will flicker red.
Bars have a white title that says what the meter is about. Water bar is titled Water, and Air Bar is titled Air. Dashing will turn the color of the bar title to Gold.
