I wrote a two page short story with this premise in, uh fifth or sixth grade (age 11, for transatlantic purposes) in 1985 or '86*
The hippie/late-boomer co-teachers, fresh from the satanic panic and countless after-school specials, called in my parents because they saw it as a sign of self-harm risk (I just thought it was funny to have Gorlox the Child wipe his blue marble clean of that icky green gunk)
Some being notices that one of the planets has "really gone off" in our solar system. The systems with big yellow suns are more prone to this issue, in fact two of the planets in this very system have need treatment recently. But this one is so far gone, that the whole thing might need to be replaced.
I love the implication that the universe may contain, and we may even to some extent recognize, something as regular, and structured as "floor tiles" but we have dismissed the notion that they were made by some other creature of greater scale simply because they are too eternal seeming and huge.
"floor tiles" are just what this part of the universe is made of, just as "boxes of cookies" are another excellent natural structure.
