Not sure what you mean by final unicorn. The toadstool that is growing will not attract any unicorns until it is ready for harvest. And that will attract the regular unicorn.
There are enchanted unicorns which are beyond that one. I checked and you have not spotted the golden unicorn or rainbow unicorn in other gardens so the furthest that you could go would be golden unicorn but since you are at level four in lengendary...I think that that holds you back as well. Each level of legendary offers you a new unicorn and I am not sure what level four would allow.
The white unicorn is the next one  for you to attract given your stats and it needs an enchanted white mushroom. So to see if you can plant for that...put out a mushroom pot aka one of the Fairytale pots and click on it...head to the mushroom tab...click on that...then click on the enchanted mushroom option and see if you can find that seed.

The stella(star) and chick will not attract anything...but they are cute to look at.I think that when you harvest the chick you get sprinkles.

I am not clear now what happens...as things keep changing. But with the aureus plants...like the one you have ready for harvest. You used to get gold sprinkles and for the first five that you harvest you get increasing amounts. Well worth planting for the gold. There are four different aureus plants and each one gives gold upon harvest...but only for the first five of each. It looks like you have only harvested one of each...so the one in the garden will be number two for that type...so still three more of that type to give gold. If they still give sprinkles...that is five gold per sprinkle...and can convert to regular gold to buy food or sprinkle in gardens.

A girl in my exercise class fell and broke her hip...had surgery...returned to class. And less than a year later, she suffered another fracture to the other hip. She had surgery again and is now doing physio. Walking...but it will be a slow recovery.

I haven't heard from Linda in awhile...suspect that that means that things are progressing nicely.

Much appreciated. Nice gems...cute little fellow. And stardust.
I am waiting for Kevin to get home from a meeting...and then an early lunch and dance class shortly thereafter.
Have you heard any further word about Dorothy?

With spotting your first rainbow chick...you should have received a stardust sprinkle. It will show up above in the light green bar...after the pink diamond total. That is the same as superfood. Do you remember what that is?

A lot has changed. No more collection of gold every three hours. No diamond sprinkling allowed. Fifty free sprinkles every day...go to the find gold page and collect by clicking on the water droplet. Regular food is free. And in about a month, you will have a birthday balloon available to you to plant...and when it is ready for harvest, you get one hundred gold coins.
There is a lot to remember...and I do not remember it all...so feel free to ask and if I know...will fill you in.
People are busy with quests...they do the challenges like the Fairytales...there is egg building right now...and there are monthly pottery lotteries. The new ones will come out on the first...and you get a pot if you attract and spot what is asked of you. There as special ones that you can win.
