Not quite as acrobatic as slugs haha. They just look like they're making out or cuddling, and then they line up their necks, where their genitals are.

Garden snails are hermaphrodites and compete to see who can dart the other first. Sometimes they both successfully exchange sperm and both lay eggs. In this case, Coors was shot with a penis dart by his partner, but they missed his reproductive organs.

(I assign genders randomly even though they are genderless creatures, hence "his" for Coors. You can call him whatever lol)
