Saddle

Saddles are items only found in the chests that are inside dungeons; they cannot be crafted. They can be placed on pigs, which allows the player to ride them by right clicking the saddle, but the pig's movements cannot be controlled by the player. Saddles cannot be placed on any other mob. The player can climb off and on the pig as they please. The saddle cannot be recovered from the pig and will be lost if the pig disappears from the map or is killed.

Trivia

 * By throwing eggs or snowballs at the pig while riding it, it is possible to ride a pig high into the air.
 * If you are riding a pig and you go over ice, your speed grows drastictly
