Actually mcpe for android did by using the app called pocketinveditor pro i was able to get a saddle but not usable atm. Which sucks because i want to ride them piggies. Lol heres a pick just yo let u know im not lying
Guys this may be possible later to ride pigs. If their is code then it may be implemented into the the game. Example: Iron Door. Is in the games HEX code. Has no working code to open or close the iron door.
