Shadowtop

Poptops are a unique monster type, found generally in tranquil environments. They wander around aimlessly whistling to themselves, but when the player draws near they get aggressive, attacking with leaping bites and now, ranged balls of tar and enhanced aggressive behavior. Poptops are astoundingly adaptive, and have shown themselves to be quite resilient when faced with even the most extreme environments. Poptops are native to worlds of forest and tranquil environments, however due to the high demand for these creatures as pets, they have been spread to many worlds and planets they otherwise never would have been introduced too. This introduction of Poptops into different environments has lead to the recorded extinction of 300+ indigenous species, countless other wildlife, and lead to numerous biological adaptations and evolution within the species.

A shadowy version of the Poptop, a Shadowtop can be identified by it’s nearly invisible, translucent body and eerie glowing red eyes and mouth. The Shadowtop runs, jumps, and lunges significantly faster, and farther than an average poptop, making this variation particularly deadly and tricky to deal with. The Shadowtop can also launch balls of tar at enemies, dealing low damage but inflicting the “slow” debuff. While afflicted by this debuff, a target will visibly drip blackish purple ichor until the effect wears off.

Luna's Lab Notes
~ The Shadowtops whistles a unique melody that shares a striking resemblance to the "....." song from the ....  (If someone could listen too, and identify the tune uploaded I can update this page with the info)  The song as reference:

~ These little creatures leap farther, and charge faster than all of their other kin, making them one of the most dangerous species to encounter - especially at night given their natural ghostly visage.
