Collections are five-piece sets devoted to specific subject-matter. Gather collections to gain extra experience.
All squirrels and Not-a-chance Hare can gather collectibles. Shamans, however, cannot gather them.
Where can I view my collections?
You can view them in the “Collections” tab in your squirrel’s house.
Yes, you can. You can gather the same collection up to 100 times.
You can exchange collectibles with other players. First of all, you have to select the items that you want to exchange (or give away). You can exchange an item only if you have at least two “copies” of it. When you’ve selected the items for exchange, click the “Exchange with friends” button.
