Someone huffed, puffed and built the pigs houses.

Three small houses - one constructed of hay, one of sticks and another of bricks - were mysteriously constructed along U.S. 35 in Greene County where a semitrailer hauling 2,200 piglets crashed last week.

Officials were focused last week on finding surviving piglets. An estimated 1,100 piglets died in the crash.

It’s unknown who built the houses for the surviving piglets.

As of Monday afternoon, all three houses were still standing and none had been blown in.
