Breeze does not move when the player sits on it, with /tick freeze, but an animation is played. At the same time, the same Warden moves.

To perform this bug you need to:

1: create a new world

2: make sure the difficulty is not peaceful

3: type /tick freeze

4: type /summon warden

5: Type /ride @s mount @e[type=minecraft:warden,sort=nearest,limit=1] or use the entity tag

6: the warden will move. if you are in survival mode it will try to attack you and give you blindness

7: dismount the warden, it will freeze as it should once you dismount it

8: mount the breeze by typing /ride @s mount @e[type=minecraft:breeze,sort=nearest,limit=1] or use the entity tag (i used this as it would work in any application)

9: the breeze will stay still but play the idle animation

10: dismount the breeze
