Winter Wonderland Event (24-Day Duration)
Edit(KP) End date: January 9, 2014 at 11:30am Pacific time.
Don't forget that for every hour you breed/plant you get 1 Present. For those that wish to be diligent (and want more apples to feed their beasties), 1-hr Bananas or Charm Cherries (only for those that have the coinage) are ideal, though most prefer 20-hr Rune Prunes to ensure they won't miss a single second of collection time Personally, what I tend to do is 1-hr Charm Cherries for when I have the time, 5-hr Spell Melons for when I need a couple of hours before I can log on again, and 8-hr Mangoes for when I go to bed. This combination works for me, personally, and while it might not be as accurate as planting 8-hr Mangoes all day or 20-hr Rune Prunes, it gives me an adequate amount of apples than if I merely planted 8-hr or 20-hr crops (not counting 5-hr Nexus Nuts, of course). Also, planting higher-yield crops should only be attempted by those that not only have Grand Farms but those that have millions in coinage to keep up with such demanding/draining prices. Let it also be said that if you only have small farms or the majority of them are small, you would be wise to upgrade them ALL to at least Big Farms --- or, if you have lots of coins to spend --- Grand Farms. The 8-hr Mangoes that Big and Grand Farms have are a MUST for those that wish to gain as many presents as possible during down time (sleep/work/etc) and are worth their weight in gold during World Events. I know that I would have personally not have met the last World Event goals had I not upgraded all my small farms to Big/Grand ones (which is all thanks to Zenobia's sage warnings/advice on the issue).
Other than that, the planting planning is up to you. Other ways to collect presents are though mining (only when you get lucky!), through breeding (once an egg is taken off the nest, the amount of time you took to breed it translates to how many Presents you get; 1 hr = 1 Present), from tournaments (when they are released) and through 4-hr collections of the Wooden Sleigh in your forest (after you've achieved your first 25 Presents).
The Community Prizes are a bit different in the sense that you need 600 Presents to unlock the ability to 'gain' Community Prizes. Once the Community, working as a whole, reaches a goal, you'll be able to collect the goal (so long as you have at least 600 Presents under your belt). This is a community effort, so the more planting/mining/breeding/sleigh collecting you do adds to the Community total. The Community usually reaches the last prize goal before it ends (probably thanks to some number 'tweaking' thanks to TL), but every little bit counts, so remember to work together and have fun!
Good luck, everyone, and I'll continuously update with new additions as soon as I'm able throughout the event!
