Help on last (black hole) level

[Kingrat]

I have completed all the levels except for the Archtrurus and the Starstuff levels. I was going to finish the game, but I can't finish the Black Hole. I can't seem to terraform or do anything with the planet under the burning house. Currently it shows as just a ghost. Am I missing something? Any help would be greatly appreciated.

Get all elements, complete all guardian levels and apply these at the black hole.

I have all elemants and completed the guardian levels. I will re-visit it again, but I am totally stumped.

Ah, right, I remember now...
One of the planets needs to be terraformed into "ghost" kind which is the white one you have by default.

Thanks! That is what I was missing. I appreciate the help.
