Also @jakemorph I think you’re absolutely right about trolls mimicking Lusii, but I think it has to be deeper than that because they also often share abilities with them, and literally blood. I think if slurry is blood they could just be feeding lusii to the mother grub to produce troll copies that can mimic them.

However, it’s also odd that Glbgolyb and Feferi have pink blood when horrorterrors have purple - maybe the lusii themselves are also mimics???
