Knock Knock question

[Lizard Sharkragon]

A question...
How many styles of door sets was shown in Knock Knock?

I've saw five styles:
1- The doors seems black tunnels, with a rock-based holder
2- The classic yellow castle holder, with black and orange doors
3- A gray holder, with brown 'wooden' doors
4- Red doors with a white holder, seeming as that 'japanese paper walls'
5- Orange mountains styled holder, with black doors with a skull drawn in it (my fav. style, is like the brazilian style Knock Knock)

Red doors with a white holder, seeming as that 'japanese paper walls'

I never remember that one

Others you missed out are:

a brown castle style holder with the black and orange doors
the starting game version with brown holders,with red doors with a yellow diamond in the middle of them
