Hoglin Exhibits Odd Behaviors

When I was playing Minecraft on my Nintendo Switch, looking around in a Bastion Remnant for loot, I spotted something odd. It's weird. It was floating, I could not interact with the blocks under it, except for TNT, I could not damage it with a sword, projectiles, or TNT. That's when I saw it float. The blocks under it were gone, but it did not fall. There were also many other things I tried to hurt it with. And it was just ONE Hoglin! Just ONE! And for some reason, when I switched to survival, it did not attack me. It did not do any animations, even though I had screen animations turned on. It just floated there, frozen in place, not reacting to anything that happened, or anything I did. I do not currently know how to show you an image.
