It drops from the Gloomy Bush. Chop it in 1 or 2 clicks per to get the most Salvia.
Where can I find the little owl, what is needed for trick-or-treat tree?
The salvia drops from the gloomy bushes. I found that I got a lot more by single or double-clicking the plants rather than doing combo-chops.
There are some Halloween pumpkins at the location that will drop pumpkins for you to use. It doesn't seem to make a difference whether you double-click or combo-chop. You will get quite a few pumpkins. But, if you double-click, you will have pumpkins that you can use right away in the pots and you won't have to transport them. They take up a lot of space in the sled.
The owls are made from salvia and pumpkins in the pots found at Nightmare. There are four of them located mostly on the right side of the map.
If you can clear Nitemare, there are a few pumpkins to chop that will give you some, but it won't be anywhere near enough.
You can put them on your wish list and ask others to give them to you, but pumpkins take a long time to grow and are very heavy so difficult to transport. It's not likely that anyone has a huge supply to give out. You can also buy them for emeralds in the cauldron recipe.
The owl, called Spooky, is gotten by first clearing Gloomy Bushes from Nitemare and combining them with pumpkins to make a potion. Then you combine the potion with worms and get Spookies.
They need to be combined in the cauldrons you find on Nitemare while clearing (there are 4).
I'm sorry, I think you might be too low level to participate in this particular event. But there will be other events and we're entering the season where they'll come pretty often.
IndigoCowgirl-Yes. The drawback of single-clicking is that you don't earn pickaxes. I've been combo-chopping everything except the pumpkins and gloomy bushes.
I 2-chopped the witches trees, as well, and was able to finish the house after doing only 17 trees. Someone else I know said it only took them 11 witch trees.
None of the items needed to make the spookies for the knock tree at home are trade-able, sell-able, gift-able, Market-stall-able.
