Pokémon transfer from rumble world to sun?

No, you can't do it. You can almost never transfer from non-mainstream Pokemon games to a mainstream game, as in Pokemon Mystery Dungeon to Sun.

Yes you can!

It's a long and glitchy process however.

First you need to have 2 shiny Pokemon (Having these 2 will edit the games code, 1 doesnt matter, one must be a charmeleon)

Then you need to go to the area where you can find articuno (I forgot what it is called)

Use your shiny charmeleon and get to the end, after fighting the boss, You need a shiny oddish, Then do the dungeon again, You should see a black box take up about 1/8th of the screen Carefully remove your wii's SD card and put it into your computer

In the root of the sd card, there is going to be hundreds of folders, Here is how you can find which one has your Pokemon on it. XXX - The amount of games you have downloaded (Mine for example is 64B, B stands for blank) 932 (If it's not after the amount of games you've downloaded, then thats not the one) The last part of the name should be AB002001. Enter the correct folder and open P01 and you should see the pokedex numbers of the Pokemon you have, followed by they're nature in all caps, followed by an S if theyre shiny or not (NS for non shiny) You can't tell which one is which if you have 2 sharing the same traits, Copy the files you want and put it into a new folder on your desktop. Next you need to swap the wii game card with your 3ds sd card, in the root of the sd card, put the files into an app like Pk3ds and let it turn the files into Pokemon, Rename those files with what you want they're nickname to be and .SM1002 (for sun) .SM1003 (for moon) I don't know how to do Ultra sun and moon, but I hope this helped! It's a bit complicated but it got my shiny gastrodon up...
