April Fools' Ultra Rares
On April Fools' Day, 2006, all ultra rare adventures became one time, and easily found for all players. However, upon defeating the monster instead of receiving the normal ultra rare item, the player received an error message. Lastly, a new adventure monster entitled Count Bakula was revealed, which resembled the Baiowulf and dropped a new ultra-rare item, the Talisman of Bakula, which resembled the Talisman of Baio but with fangs. This all happened before The Master Of Thieves, The Temporal Bandit, Pooltergeist, Knott Slanding, or The Nuge existed.
Also, one did not receive a consolation ribbon when one was beaten up by an Ultra-Rare monster, mainly because consolation ribbons had yet to be implemented to drop from them.
