Spawn mob riding the player

[FlapKakker]

Hey, I was wondering if there is any syntax available in skript to spawn a mob that rides a specific player? I'm trying to add some text above or below a player's displayname and was wondering if I just could spawn in an invisible mob (slime, chicken, what ever) and add a specific name to it (e.g.: Level 1, point is to display the level of the player above or below his/her display name). Additionally, I would make it so that the direction the mob is facing is the same as the direction the player is facing.Thanks in advance.

I know an option exists to bind a hologram from Holographic display to a player, but the issue is that whenever the player moves, the hologram moves behind it with a little delay. I'm looking for something without the delay.
