It was a spooktacular day at the Pru on Sunday as legions of ghosts and goblins hit the posh center to show off their Halloween get ups and stash some treats.

There was face painting, pumpkin decorating, magic shows and a musical performance, all free. Parents, many also in costume, were just asked to buy a Prudential Center trick or treat bag for $5 to benefit Boston Children’s Hospital.

The so-called PruBoo festivities celebrated their 30th year on Sunday.
