Under the Leaves

You may place any market tile so that at least one full side is adjacent to a tile you already placed; terrain colors or puddles do not have to match (tiles form a grid and must touch one full side) (page 3).

Bees arrive when you create a pollinated area of 3 or more continuous same‑color terrain spaces; place a bee in that newly created pollinated area and in any other pollinated areas of that same color you already have, but you do not add bees when you merely enlarge an existing pollinated area (page 4).

A tile attracts a hummingbird when all its terrain spaces are part of pollinated areas (if the tile has a puddle, only the three terrain spaces are considered); additionally, forming a row or column of three tiles that have attracted at least one hummingbird gives the middle tile an extra hummingbird, for up to three hummingbirds on a single tile (page 4).

Each combination of terrains can fulfill a leaf‑dweller criterion only once unless the card says otherwise, but a single terrain space may host different types of dwellers simultaneously (page 5).

Some mushroom dwellers (e.g., HOST) do not require pollination and are attracted by mushroom patterns, while puddle and mushroom cards list their own specific conditions; note that some effects (for example DIVER) only trigger when the puddle is first created and will not attract new dwellers if the puddle merely grows later (pages 5–6).

The game ends when the bag runs out and the market cannot be refilled (after 12 rounds / 13 tiles each); players with a majority of a dweller type each take two extra pieces of that type (ties give the bonus to all tied players), and final ranking is by total creature pieces with ties broken by hummingbirds, then bees (page 5).
