Interestingly, these items will all only be available in the game's store for the next week, while the first set of April Fool's Day items (which was released in late March) will still be around even after that. Since your time to purchase these items is rather short, and there's no guarantee we'll ever see them released in the game again, make sure you purchase the ones you're interested in now so you don't regret skipping them later on.
What do you think of these presumably final April Fool's Day items? Will you purchase any of these whimsical trees for your collection(s)? Sound off in the comments.
