What are we looking at exactly?

My guess is that it's something to do with them being out in the water, on a boat, and the mini map says they are in Meadows... but also maybe the fact that (judging by the large pillar stone in the background), they are actually in or approaching Plains.

I often find small patches of meadows along the edge of plains biomes.

Yeah it would help if OP would actually make a statement rather than just posting a vague, random screenshot.
