Minecraft - dragons?

I have Minecraft on my cell phone and wanted to ask if you could hatch the dragon eggs in any way or not. - Thank you

And another question would be:

There's a horse mode called SIMPLY HORSES on YouTube, does anyone know how and whether I can download it on my cell phone?

Even in the Java version, you can't hatch the dragon egg… The egg is more like a trophy.

But you can respawn the dragon

Unfortunately I can't answer you
