Terracotta sprites are usually unfriendly, but mostly when you pull on their leaves by accident while they are buried >w<. Otherwise they just do their own thing

Truffle sprites are friendly though don't come out often. If one finds you it may begin to follow you for awhile, hoping u will give it some compost.

Marimo sprites hang out in ponds and lakes though u may not know if you see one. Usually they sleep underwater and only their fluffy green tail at the surface. They also tend to do their own thing, but may play tricks on you if they are bored or you make them mad.
