What is the purpose of filling containers at Peka Glade (if they're not thee Ornate Floral Pitcher, which makes Glade Potion)? Do they do anything special?

They have no use apart from being nice treasure chest or gallery items. Who knows, maybe they'll have another option someday in the future but at the moment there's actually not so much sense behind them. C:

Ah...okay. Thanks for the help. :)

you can feed them to your pets too, but they are no more than that... food.

I figure they are worth getting a few each, in case in the future they become a wearable or are used for something useful.
