I bought this set at a car boot sale the other day and I can't find anything about it anywhere. There's no set number. It comes in a long plastic pinch bag with the parts and a small sheet of instructions. The bag is dated 2017 but there's not much more information than that. I tried looking on bricklink at all the sets that contained a blue 6x6 plate but it's not on there. I thought maybe it was a monthly in store mini build thing but I can't find anything on google.
