The Nether Stalker is a spidery mob found in warped forests in the Nether. It can jump a great distance or hang upside-down on surfaces.
The Nether Stalker is hostile, making it the only hostile mob currently found in the nether's warped forests. It will jump up and attempt to land on the player, dealing 9 damage (8.5 hearts) on hard mode. Nether Stalkers are immune to fall damage, and can climb on the ceiling and spot the player from a huge distance, often resulting in them dropping down from above unexpectedly.
The Nether Stalker has a green body similar to the huge warped fungi found in its natural habitat. It has a white eye covered in red irritation and veins, with a black pupil. The eye can rotate independently of the "torso" to always look at the player. The Nether Stalker has four legs projecting out of the "top" of its body and bending down. It will flip over 180 degrees, turning upside-down, when it is climbing on ceilings.
