With so many other shows apparently hopping on the brony bandwagon lately, it wouldn't be too surprising if this colorful unicorn conjured up by Lisa's saxophone was a reference to MLP. The image above is from the 6th episode of the 26th season that aired a few days ago, a Futurama crossover.
Now we just need that Southpart episode. When is it going to happen?
Thanks to Welliam for the image.
