Can't fully complete either the Fairytales or Butterflies.  Close on both by 1 or two sections.  How to gain and replenish Toadstools and Rubies?????  I am dead in the water.

Now's a great time for hunting to build up diamonds, supershroom seeds and jewels. You'll gather more then you think if you focus on hunting - the seasonal is great - but think of the regular that have albino/melanistic (fox, squirrel, raccoon) and hunt those as well.

I remember having similar issues a few years back.  Focus on other wildlife, and then one day, you’ll realise that you have naturally replenished  enough seeds to complete those two challenges. Meanwhile, enjoy spotting festives to hopefully give you a good head start xxx

This can happen at anytime with this game. You just have to pause those particular tasks/challenges and focus on something else while you replenish needed resources.

The Butterfly flowers need only Forest Rubies and those are very easy to find right now when everyone is hosting seasonal pests.

The Fairytale seeds are a bit rarer but after the Holydays rush is over, I'm sure plenty of people will continue with Fairytales and animals that have albino/melanistic versions.
