This was going to happen yesterday, but because Chase went ~drama llama, Sirius decided to wait a day. Now that Chase is going to be okay...
SIRIUS HAS UNLEASHED 2000+ BILLYWIGS ON THE SCHOOL, as of right now. They will probably stay around til Monday/Tuesday. In short, Billywigs sting cause giddyness. Enough of them cause you to float. If you have an allergic reaction, you will continue floating until you get treatment. BASICALLY, everyone is going to be high. You don't have to have your character stung, but you do need to come up with a valid reason why they weren't.
