Spoiler: it's a Zombified Mountain Stone Weta (Hemideina maori) infested with parasites

Lol a Weta is a type of insect native to New Zealand. The ones that are hard to kill are listed as hard to kill in part because they are infested with a parasite that will basically enslave the insect, taking control of its nervous system (or something), and forcing it to behave in certain ways - often even after death

@mia_linay posted a gif some time ago on her mialinay account of what seemed to be a Zombie beetle

“Infested with parasites” like you can see them wriggling under the skin

And I use a bucket to cover a little hole in my bathroom everytime i shit because i am afraid a cockroach might show up
