Mystery cargo

I just solved the mystery!!!! Off of a bob the builder toy. I only remember hay bales looking like that in the show, whereas Google finished my questioning.

I thought so, too, but it looks like they came from some sort of other BtB merchandise. The ones in the Travis image look slightly different to the ones Chrisjo posted, and they would be larger than the ones in the TOMY trucks since Travis is Born to Play scale. I never had the trailer and hay bales and got Travis in a set with Scoop.
