She sends mail to all players in an urgent action bulletin:
URGENT ACTION BULLETIN
The orphans of Northrend need your help. For less than the cost of a cup of [Kungaloosh], you can sponsor an unfortunate orphan like little Roo or Kekek. Simply contact Orphan Matron Aria in Dalaran. You can make all the difference in the life of a young oracle or wolvar. Act now!
We are presently aware of an issue which is preventing players from completing the quests Little Orphan Roo Of The Oracles and Little Orphan Kekek Of The Wolvar if they completed either quest last year. While we do not have any specific details to provide in regards to when this issue will be resolved, we will keep you updated with the latest information as it becomes available.
To clarify, this issue won't be able to be resolved for Children's Week this year. If you completed the quest previously you won't be able to complete it again for the other pet this year.
