You have been invited to a party to the fabled Cloud Cuckooland, hosted by the ruler, Unikitty, the invitation says that many characters of many IPs will be attending the party, so thats why you have been invited. That's exciting!

A few hours go by, and you somehow arrived at the doors of Cloud Cuckooland, and there is a rule list by the doors. The rules are: No frowning, no negativity of any sorts, no verbal harassment, no bedtimes, and no attacking anybody. Failure to do so will result in DIRE punishment. Pretty straight forward. Do you knock on the door? (Hint: the secret knock is just to knock on the door ONCE.)
