Zooloretto

Yes — when you take an untaken delivery truck you place it (and all tiles on it) in front of you and must immediately add those tiles to your zoo following the placement rules (animals to empty enclosure or barn, stalls to stall space or barn, coins to your money) (page 2).

No — an animal tile may only be placed on an empty enclosure space or in your barn, and no enclosure may contain more than one type of animal (you may have multiple enclosures with the same animal type) (page 2).

Yes, placing a tile on the last empty space earns the enclosure’s coin bonus, but there is an exception: you do not receive the bonus if the enclosure is filled as a result of an Exchange action or if an offspring is produced by an Exchange (pages 4 and 6).

No — you need only one vending stall adjacent to that enclosure to score when it has two or more empty spaces; with one empty space you score the lower enclosure value regardless of stall count (pages 4 and 6).

No — you may not move an animal from an enclosure to another enclosure or to the barn; the Remodel 'Move' action only moves a single animal from the barn into an empty enclosure (and vending stalls may be moved), while an Exchange swaps all tiles of one animal type between two areas and requires animals in both areas (pages 3 and 6).

Each animal type present in your barn scores −2 points, and each vending stall type in your barn scores −2 points (page 4).
