 * The temperate variant is orange, the warm variant is white, and the cold variant is green.
 * Frog variant depends on the temperature of the biome where it turns from a tadpole to a frog.
 * Each variant is planned to have a unique use for players, which remains unknown.
 * One known use is Froglight production.
 * Jumps on lily pads and big dripleaves.
 * Has the ability to swim in water.

 * Tadpole.png
 * Grows up into a frog after birth. Frog type depends on which temperature it grows in.
 * Can be held in a water bucket.
 * Panics on land and pathfinds to a nearby water source.
 * Also panics if there are axolotls nearby.


 * Warden.png Warden
 * Spawns in the deep dark biome, specifically when too many sculk shriekers are activated.
 * "Emerges" from the ground when spawned by sculk shriekers.
 * Digs back into the ground when it doesn't sense any vibration after 60 seconds.
 * The first fully blind mob (bats have basic eyesight, both in-game and in the real world).
 * Because of this, it stumbles as it walks.
 * It can also detect players or mobs that have the invisibility effect.
 * Has a sense of smell. It can detect and pathfind toward the general location of a player or mob through a "smelling" action.
 * Prioritizes smelling the player or mob that it is most suspicious of, rather than the one closest to it.
 * Has a sense of vibration. When sensing movement, it pathfinds toward the source of the movement.
 * It follows and attacks players, mobs, and other entities that make vibrations.
 * It does not attack other wardens.
 * When it detects a vibration, the growths on its head rattle and light up, similar to the sculk sensor.
 * Seems to follow the same rules as the sculk sensor when detecting vibrations.
 * If any projectile (e.g. egg, snowball, arrow) lands near it, the warden inspects the location where the projectile landed, due to the projectile creating significant vibrations. This feature can be used in order to cause a distraction.
 * Becomes more suspicious of a player or mob as it detects its location more through vibrations and/or smelling. When it suspects the target enough, it identifies its exact location, which aggravates it, causing it to pathfind toward the target to attack regardless of outside distractions.
 * It is the only mob that spawns in the deep dark biome.
 * A mob designed to be extremely difficult, intended to be avoided and fled from.
 * Has a way to counter "cheesing" strategies like pillaring up to avoid attacks. The solution does not involve block breaking. rather, more related to psychological effects.
 * Incredibly strong, doing to  damage.
 * Currently has health points.
 * At least as fast as a walking player.
 * The warden doesn't qualify as a target for the advancement "Monster Hunter" and isn't needed to receive the advancement "Monsters Hunted" due to its role.
 * Warden's chest has a glowing core that appears to brighten and dim in tandem with the Darkness effect.
 * The core creates a low throbbing or "heartbeat" sound as it pulses. The sound and animation speed up rapidly as the warden gets more suspicious of or closer to attacking a player or mob.
 * Is about 3.5 blocks tall, making it one of the tallest mobs in the game, exceeding the iron golem and enderman in height.
