Okay, I've completed the floating waterfall quite a while ago. Question: what are those sparkle seeds for?
They're filling up the gift box.

I've asked that before and still havent had an answer! Hope they are for something good

I've been either regifting them or selling them for the extra coin.

Do you mean that we need Sparkle seeds to build a Waterfall that produces Sparkle seeds?

Maybe we're gonna be able to plant them and have them grow up to be baby VAMPIRES..? After all, they seem to SPARKLE these days.. ROFL...
