Snow Covered Diesel?!?

This is actually the Diesel from the Fisher-Price Target-exclusive “Devious Diesel and the Troublesome Trucks” glow-in-the-dark pack. It included this variant Diesel and two Troublesome Trucks with glowing loads. I believe those trucks are also the ones you have, without the loads. From what’s included in the pack, I would guess the little specks on his side are actually supposed to represent quarry/rock dust as opposed to snow (one of the trucks is carrying stone), although almost all eBay listings call him “Snow Covered Diesel”. And sorry, he’s not that rare; there are currently quite a few for sale.


What I’m interested in is does any part of the Diesel actually glow? The Wiki says it is a “glowing Diesel” but I haven’t been able to find anything about the Diesel actually being glow-in-the-dark, just the trucks’ loads.
