So I was trying to justify a cyan grue to a grue enthusiast, and asserted that it is a BABY grue, and thus turns black when it gets older, like a black panther. (Besides, YOU try to train an adult grue!)
Thus I went a-Googling for “black panther,” and I found this on Ali Baba:
Death Bed: The bed that eats people
In the thumbnail it looked like the whole bed made a single panther face.
You have offsprings.
You mod their plain sheet set so each pillow looks like an eyeball and the comforter looks like a mouth.
Now their bed looks like a big monster face.
You can make it scary or friendly depending on how much you like your offspring.
You can use it as a defense against closet or under-bed monsters.
It could be a breakthrough in preventing monster attacks.
