Yes some pigs do play with toys.
Then again some pigs may just want to be lazy and not energetic but it really is all up to the individual pig.
I've been around pigs on a farm as a kid and the pigs we had were mostly playful and energetic pigs and they had dog toys that they would love to play with.
I had a pig on the farm that would chase after a ball and then roll it back to me and then want me to throw it again.
Or I would throw a Frisbee and the pig would go after it and bring it back to me.
Then there was a pig that we had that was so lazy and didn't want to do much of anything.
Just like some people are energetic and some people are not.
Pigs are the same way as are some other animals.
