Dichanthelium lanuginosum
Dichanthelium lanuginosum is a species of grass that can survive higher temperatures than it normally could, if it is colonised by a specific fungus and if that fungus is infected by a specific virus.
Perhaps something similar is going on with Skibidis being much stronger than untransformed humans. (I already headcanon that skibidification is fungal, because I like fungal horror as a trope.) Perhaps that's why G-Toilet chose Earth to invade. Maybe there's something about humans that produces strong Skibidi Toilets, capable of standing up to the Astro empire.
