mind-controlling parasites... this parasite is called Leucochloridium paradoxum. There are many other "mind-controlling" parasites such as the Spinochordodes Tellinii which infect grasshoppers and forces them to drown themselves... (Where the worm reproduces). Oh and one of my favs is the Toxoplasma Gondii found in cats intestines. But I'll let yall look it up. Savor the knowledge my children.
