Of all the variants of “MLP urinal trough” I tried (to fulfill the request made in the comments of >>3092239), only two images fit the criteria for inclusion here. All the rest merely took “My Little Pony” and its variants to mean “pink and purple colors,” but no actual attempts at ponies. V1 would have made grade-A body horror fusions.

The AI couldn't decide between drawing urinal ponies or just drawing ponies inside the urinals.
