how do i stack multiple mobs in the new minecraft updates?

Question

In the new update I think 1.8 - 1.12 (now) there is no way to stack mobs, there is passenger but if you try more than one mob they get stuck together and I am hoping there is a command out there that will stack higher and not smoosh mobs.

Answer 1

You do this by giving the passenger a passenger. And that passenger another passenger. Etc etc.

So for example:

/summon chicken ~ ~1 ~ {Passengers:[{id:"chicken",Passengers:[{id:"chicken",Passengers:[{id:"chicken"}]}]}]}
