Horse saddles

Horse saddles were items that were added along with horses that worked just like regular saddles, but for horses instead of pigs. Taming a horse is required before putting a saddle on it.

When horse saddles were placed on a donkey, a chest can be placed for on-the-go storage. However, the chest is currently inaccessible.

Horse saddle items were later removed from the game, and the same saddles (found in dungeons) are now used for both pigs and horses.

Usage and behavior
You would place a saddle on a tamed horse to be able to ride it. You could ride it by right clicking on the animal and using the regular control keys. When you were done, you could press the shift key to dismount. The horse would drop a regular saddle when killed.

Note: only fully grown horses could wear the saddles.
