With the Horse Powerups mod, your horse will be “pumped” in Minecraft Bedrock Edition. Unfortunately, he will not have more HP (and it’s a pity, a tenacious horse would also be good), but you can attach some unique abilities to him in Minecraft on Android. How do you like the idea of making it fly?
Inventory of a horse in Minecraft now includes two slots, in one of which a saddle is placed, and in the other some kind of block. For the Horse Powerups modification to work correctly, you should enable experimental settings in MCBE. The mod works in the game exclusively on the release version 1.18. Have a nice game!
