If you have at least 1 Building (blue tile) in your hand for which you meet or can meet the playing condition, you may play exactly 1 such tile in this step. Place it on an empty space on your Zoo map (adjacent to either another tile or your zoo entrance) which meets the condition to play it on the tile, if applicable.

If placing the tile triggers effects (one-time effects, ongoing effects, or placement bonuses on the Zoo map), you may perform them in any order.

EXAMPLE: The Tree House must be placed next to 2 tiles with a Forest icon (A). You play it on an empty space between the Dusky Leaf Monkey and the Great Hornbill, each of which has a Forest icon on their tile (B). Because the empty space shows the icon as a placement bonus (C), you may take any 1 tile from the display.
