It appears as though these three Circus dragons (Circus, Acrobat, and Illusionist) are now breedable on Android, as the message "not available through breeding" no longer appears in their descriptions. The advertisement says that they will be on sale until Friday, but it doesn't say whether or not they will also expire at that time.
Kooky or Elsa, can you please confirm if these will expire again on Friday, or if it is simply the sale that will expire?
