How to make mobs upside down while riding a bat

I am wondering if you can make riding mobs of a bat upside down, I saw a video where a mob was upside down and wanted a code to make it. I want the bat to be invisible and invulnerable and another command to not be invisible, but still invulnerable. (2 commands)

Invisible Bat:

/summon Creeper ~ ~2 ~ {Riding:{id:"Bat",Invulnerable:1b,ActiveEffects:[{Id:14,Duration:9999999}]},CustomName:"Dinnerbone"}

Not Invisible Bat:

/summon Creeper ~ ~2 ~ {Riding:{id:"Bat",Invulnerable:1b},CustomName:"Dinnerbone"}

Of course, the coordinates can be changed to your liking.
