observation results 1.When I was fighting the Ender Dragon, I noticed the Ender Dragon's behavior was strange, the Ender Dragon landed longer than usual, and the Ender Dragon didn't react to me until the end. I could easily kill the Ender Dragon.And it doesn't seem challenging to me because the Ender
Dragon is too easy to kill and he lands too long and doesn't fly or counter attack the player
2.Dragon's breath does not deal damage to players.

expected results The Ender Dragon should not land too long, it should land for about 10 seconds and attack the player back by spitting fireballs at the player or flying at the player.And dragon breath should be able to damage other players or mobs.
