Blue Plastic Tracks

So I was scrolling through the internet and I found this, a separate sale metallic Clarabel. I did not know this existed until now, can anyone identify where this comes from, is it rare, or anything about it?

This was also sold or given away with a metallic thomas too which can be seen on the top of the clarabel box. However there was no metallic Annie given away which I find very weird and interesting. I do not know why these were produced or where they were given away but would love to know and find out

Thank you Thara

Interesting. Things are strange sometimes and its hard to figure out the why's and what for's they do things like this.
