the name attributed to cloudy copter in baldi's basics plus in the game files
you may think this is some sort of silly cum joke but no and people who actually payed attention in school would know what it means, both of you.
This name is derived from the word "cumulus" which is a type of cloud that looks like multiple puffs of vapor mashed together, and if we look at cloudy copter itself you can see that it is indeed a bunch of 3d spheres mashed into each other
