Vanilla
I believe that some players of Minecraft PE have at least once pondered the fact that zombies lack the ability to infect other entities. Therefore, today we introduce to you the mod “Vanilla+” for Minecraft Pocket Edition, which will implement several changes in the game and allow zombies to infect horses, transforming them into zombie horses. Now, you’ll need to be concerned about protecting your steeds during your travels, as you never know if your stallion will be healthy upon your return. This is certainly a worthy addition to MCPE, bringing sensible modifications to the gameplay.
From now on, zombies will always be hostile towards horses. After a few hits from an infected horse, it will change its appearance and become infected. Subsequently, they will die within 20 minutes and then turn into a real living skeleton.

If your beloved horse does get infected, don’t worry, as you have a little time to cure it. First, throw a weakness potion at your steed, and then feed the animal a golden apple.
The healing process takes a few minutes, so if your horse doesn’t recover immediately, there’s no need to panic. Just engage in some productive activity in the world of MCPE during that time.
