This character is certainly findable, but they tend to run hot and cold - your chances of meeting them can vary by the week (or even by the day!). Know where to look, and be patient.
Where to find this character:
Rosetta is available on some days along with Tinker Bell at the Adventureland Verandah - just as you cross the bridge from the castle, this indoor location will be on your right.
Tinker Bell is always available, but you can never predict which of the other fairies is meeting with her at a given time. Usually, there will be one; every now and then, you might get to meet two.
Rosetta is the most difficult of the "normal" fairies to find.
