I have seen a few things in the Store that I am not sure what they do or are used for etc:

Perfume
Desensitization Kit
Mega Chamomile extract and Chamomile extract

Is there a list somewhere that tells us what these things are used for?

Does the Tool Box DO anything?

Thanks Ever So Much

Those items all have pretty good descriptions of what they do when you click on them in the store.

What are....the red things that go over the house occasionally? Birds? lol

Yes, afamilysomeday, they are. If you have played VV2, you'll recognize them as the same type of birds that hung around Isola

What is the turtle adventures from the store?

Like LadyCFII said, if you click on an item in the store, it'll show a description of what it is.
