I think mood scrolls are showing up less and less each week is because they plan to remove them soon and implement the new system for moods. I would be happy with a new useful ninja that hasn't be implemented into the game yet, so people won't get dupe ninja's like lucky cat. I got him from merge event and I think christmas, so he is almost 4 starred xD. Guess we will find out tomorrow maybe since anniversary events should be listed tomorrow.
