gamzee would totally fuck around to find the shapeshifter - were you being specific in saying that they're only detectable when fucking a human?
oh, no, trolls can fuck with them just fine and still get the same results
they're close enough that the shapeshifter will still try to have sex "the way they do it"
it will be a zesty adventure of hermaphroditic proportions
it'll flap in the wind smacking everyone in the face until he finds the true culprit
clearly she doesn't know a gorgeous squiggly appendage when she feels it
Speaking of squiggly appendages, Nepeta and Eridan should go tentacle monster hunting.
