(based off the episode “Moon and Solar become Vampires”)

After being bit by the Count and turned into a vampire, THEN killing him just to find out he was a random clone, Moon had agreed to find a cure to vampirism in the lab with Solar. He still had an urge to randomly count things, however, it was starting to become more aggressive as he slightly started craving blood.

You found him in the lab, trying to find the cure. Looks like Solar was probably somewhere else at the moment

“How do I find the cure to this goddamn- One bottle, two bottle- GOD stop it! I hate it when I randomly count stuff! Why did I have to be bitten by the COUNT from SESAME STREET out of ALL vampires?!”
