Does anyone have a link to any post about strategy for the pinatas? Or is it just a pretty straight forward event

Yes, Pinatas are free unless they changed it. The last Pinata has a 1600 points requirement, but with strategy you'll be able to finish it by Sunday/Monday morning according to your time zone, so you should be golden.

Usual rules:
- Do objectives before clicking ANYTHING on your Pinata
- If you can, validate objectives that affect your bar before the timer gives you another life
- Have at least 10 friends that can and WILL click on the pinata as needed.

1) Pinata tutorial
2) 30 points
* Stroke a horse / * Put a pony to bed

3) 50 points
*Visit Ow's page / * Congratulate a player

4)80 points
* Choose a horse speciality / * Click on a friend's pinata

5) 120 points
* Give an apple to a Divine or Wild horse / * Donate money to Ow

6) 200 points
* Get last place in a competition / * Use an aging point on a 15 years old horse (this is on the dot, it must be exactly 15)

7) 300 points
* Be congratulated 5 times / * Donate to a new player

8) 500 points
* Feed a Pegasus / * Win a number of competitions

9) 800 points
* Buy a horse for an amount of eques / * Donate money to Ow

10) 1600 points
* Use a customization item on a horse / *Give birth to twins.

I cannot stress it enough, all objectives must be done AT THE EARLIEST, especially before clicking anything on your pinata. Objectives ALWAYS first.
By doing it all religiously, you should be certain enough to take the Fala home for free

To get the Falabella from the Pinatas, will it require setting timers to click them as often as possible like in previous events? I really want that Falabella, but I also don't want to have to be on Howrse in the middle of the night

If I recall correctly, you just need to make ABSOLUTELY sure you'll pass the second Pinata before the update (or you'll mess up the Friend clicks).
The more you proceed, the less punishing it becomes (missing a click the first day, with clicks given out every 8 hours, is ATROCIOUS compared to losing one the last 2 days, with clicks every 2 hours).
At least for the first few days, you REALLY have to keep pace or you'll mess up.

However, since you live in Australia, the times shouldn't be in the middle of the night for you, for the first few pinatas

Will there be a step by step kind of routine put out when the piñatas start?

I mean, they're pretty intuitive, but I'm sure ShadowKofuku has some general tips. Just remember to do the tutorial, do your objectives BEFORE you start pressing and asking for help and then reach Pinata 3 before the update.
In case there's need of it, I think we can put out a day-by-day pace manager as we did for the Axolotl Castle?

Would I be too optimistic if I hoped they did the same greyfell and pinata points promo in the GF as they did before in the pinatas event? I've not been able to get a new Greyfell for the longest time

Yes, since the Divine is in the TCs and not in the Fleeces, and since you can't have 2 Divines in the same luck item.
There is no pinata points in the Challenges.

TIPS:
-Make sure that your click meter doesn't fill up all the way. If it does, then it will stop regenerating clicks and you will be wasting the time in which it could potentially regenerate new clicks.

- Read BEFORE you click! Every time you unlock a new pinãta, you may want to check the objectives that come with your pinãta BEFORE you use up clicks on that piñata. For example, you could have an objective that increases the amount of points that each click is worth. And if you just start clicking your piñata immediately without checking your objectives and seeing that reward, then you may end up using clicks that are worth less points when instead you could have just completed the objective and used those same clicks that would then be worth more points.

-If you can't do an objective, then just donate a low level BMI (eg A. Lyre) to Ow. That would have the same effect as completing the objective and you will still get the reward.

-Every time you fill the click meter for a piñata, you need to collect your earnings before you can move on. So if you're stuck on a pinãta after you filled it's meter then it's probably because you haven't collected your earnings.

-You can only unlock 1 piñata at a time in the order that they are given. The rest of the piñatas' objectives and click meters will not be accessible until you have finished the previous piñata's click meter and collected your earnings.

-You cannot go back to complete objectives that you skipped after you move on to the next piñata. So I would suggest that you do the objectives that you get with your piñata ASAP because you will not be able to collect the reward that the objective offers after you move on to the next pinãta.

-You can help your friends out once per day by clicking on their pinãta through your piñata page (if they request help). You can also request help yourself. The amount of requests that you can make per day depends on how many objectives you have completed to earn more requests per day. If you don't have friends, then I recommend posting in the 'find a friend' forum to help you find friends.

-You cannot replay the promo once you complete it.

-When an objective asks you to spend an AP on a horse that is 15y old, then you need to spend an AP on a horse that is EXACTLY 15y old. If you age a horse who is 15y Xm old or older/younger then you won't complete the objective. Or you can just use a BMI.

-The promo offers you a free divine falabella as a final prize! This is a rare opportunity nowadays so why not take advantage of it and go for the fala? He's free after all

-There's no community piñata for this event.

-This promo CAN be completed without the use of passes.

Button Plaiting prize? I agree its too ugly to talk about but still..I advise you use it on draft horses,they look semi okay (sorry if someone already mentioned this)

In the isolated kingdoms event, they are bringing out yet another tack set item...does anyone know if this saddle is going to be joined by a bridle,wraps,ear bonnet in the next events?

They are. I have found all the tack pieces in the site. They're not up yet (no description or image), but there's a dedicated page with the +10 bonus in each skill for them

the Button Plaiting, was talked about during the testing of the Pinatas event last month
I think some players showed screenshots on the different breeds, but I'm not sure if they were included in any of the masterposts, so they may have gotten buried.

, The Knight's Saddle was just introduced in the current test session, and all we know regarding future pieces is that "This is a brand new tack item from the new Knight's Equipment set. Different pieces of the set will be offered in later promotions." So we'll be getting more pieces as time goes on, but it's possible we won't be able to combine pieces of the set like we can with the Legendaries as Admin's post on it says "cannot cumulate with another equipment of the same type." We haven't yet had official clarification on this yet

So it’s the piñatas next yes?

I would love to ask you if does anyone of you think that there is possibility that some of the solar divines will be hidden in HoP.. In my opinion it's almost impossible cause these divines are so valuable but I would love to here your opinion. Thank you for your answers

Almost impossible in my opinion. They're very valuable Divines, they'll probably put them in Fleeces or Challenges.
