The animals section of the Stronghold 1 editor allows you to place several types of animals. The animals you can place include crows, rabbits, seagulls, deer, bears and wolves. Note that all flying animals cannot be seen in the editor when placed:
Animals are very sueful for bringing your map alive - and in the Stronghold 1 editor there is the unique ability of the animals being able to move around. Rabbits, Bears and Wolves show this feature off especially well. I stringly recommend that you incude as many aniamls as possible in your maps - they really bring it alive!
