Blue Plastic Tracks

Did I miss something or is it just old age? I have seen the Disney Action Advertisement Car (blue one) but I am not remembering ever seeing the Yellow 'Zoo' one. Can anyone share some info they may know of on this?

Which brings up another question:
How many of these rotating Ad cars have been released. I think there was also a Fish one too but are there more?

The newest one is the one from the "Hiro and the Aquarium Freight Car Set", I think:

Thanks Mr No...thats the Fish one I was thinking about. Ucwepn has an Unboxing video of it. https://www.youtube.com/watch?v=3hwYtpQvJdk&t=126s

Further searching resulted in finding the Yellow Zoo one but is this Zoo Gordon set readily available or a bit harder to find?

@Super, it can be a bit harder to find, though it's being sold for ridiculously high prices.

Thanks GG-Fan
It certainly seems like there aren't many around. Looking closer at the Gordon that comes with this...looks like a regular Gordon with a few Bunting stickers on the boiler and a couple of Lion stickers on his Tender.
