Squirt
The Squirt is a medium-sized poop enemy that does contact damage to Isaac by periodically dashing to him. Two Squirts spawn from 
Dingas when killed. It splits into two 
Dips when killed.
Variants
Dank Squirt
Dank Squirts dash towards Isaac, leaving a trail of slowing Black Creep. Upon death, they spawn two 
Clots.
Splurt
Splurts are a variant of Squirts that dash twice towards Isaac rather than just once and can travel over flooded pits. Upon death, they spawn two 
Drips.
Hardy
Hardies are a rocky variant of Squirts.
They charge at Isaac, and if they run into an obstacle/wall, a piece of them breaks off and rock projectiles are fired outwards. A Hardy will destroy most breakable obstacles on collision and is also able to reveal secret rooms if it hits the entrance of one. After running into rocks/walls three times, a Hardy will die.
- First collision: 8 rock projectiles are fired out in a radius.
- Second collision: 8 rock projectiles are fired out in a radius and a cluster of rock projectiles is launched in Isaac's direction.
- Third collision: A cluster of small and large rock projectiles is launched in Isaac's direction. The small rock projectiles have shorter range and will spawn 2-3
Rock Spiders and the large rock projectiles each shoot out a small cross of 4 smaller rock projectiles upon landing.
In the uncommon event that it charges but doesn't hit a wall or obstacle, it will slow down like a normal Squirt without sustaining damage. Upon death, it spawns a Dip.
