The moon is a quintology thing. Abe and Munch already have two moons.
Now, it seemed corny when Munch got one. You want a third moon for Stranger? And with what? A hoof print? Nah, come on.
And besides, take into consideration that moons control...planety...stuff. Like tides. Mudos would be underwater with that many moons.
We're gonna run out of moons quickly. And do you know how hard it is to keep burning those foot and hand prints into the moons with a laser?!
