Okay, so I decompiled this model with Crowbar to "enhance"
's Night Light (aka Mr. Sparkle) model. I edited the .QC file of the decompiled model to accept Night Light's mane, tail, and textures, then recompiled.
So far, the results are good, and the model functions as expected. Though for some reason, the mane and tail jigglebones aren't working. Only the tip of the tail wants to "jiggle," while the rest of the mane and tail refuse to obey physics. The ear jigglebones are fine, though.
