FOSS gamedev and creative worlds

I used the /giveme command to get a cloud block. I placed it down on my glass house and it won't come off D: I tried using a shovel, mese pickaxe, lava, and torch but it won't come off for anything! Does anyone have any idea on how to get rid of it? Please and thank you!

The cloud block cannot be removed; if you want to remove it forcibly, you can use the WorldEdit mod:

I thought I'd never get rid of it, thanks a bunch! :D

Also, cloud blocks can be used as a wall to keep griefers out - they can't break it.
