You must place the following Buildings on a space on your Zoo map that, in addition to the normal placement rules, also fulfills the stated placement condition:

Place this Building so that it is directly adjacent to at least 2 tiles with the depicted icon (in this case, Water). The tiles you place the Building next to do not have to be directly adjacent to each other.

Place this Building so that it is directly adjacent to an area consisting of at least 4 connected tiles with the depicted icon (in this case, Forest). The Building must be directly adjacent to at least 1 tile that is part of the connected area. For the definition of connected tiles, see the Scoring section. You may not place the Building in such a way that, only through the Building, 2 smaller areas are combined to form the large area needed to play this Building.

Place this Building so that it is directly adjacent to any combination of at least 4 different animal class and/or continent icons. Other icons such as habitats, Project, or Building do not count.

Place this Building so that it is directly adjacent to the River on the left or right edge of your Zoo map. This means that you may only place this Building on the 3 spaces on the left edge or the 3 spaces on the right edge of your Zoo map. You must still place the Building on an empty space adjacent to a tile already on your Zoo map. At the start of the game, for example, you cannot yet place this Building (because your entrance is too far away from the River).

You may place the following Buildings on an empty space of your choice that fulfills the normal placement rules, provided you also fulfill the stated playing condition:

To play this Building, all 6 spaces by the River must have tiles on them. These are the 3 spaces on the left edge and the 3 spaces on the right edge of your Zoo map.

To play this Building, you must have all 5 continent icons or at least 5 different animal class icons (of the 6 available) on tiles in your zoo.

To play this Building, you must have at least 7 tiles in your hand in step 3. of your turn. This tile itself counts toward these 7 tiles.

To play this Building, you must discard 4 other tiles of your choice from your hand. If you have fewer than 4 other tiles in your hand, you cannot play this Building.
