Unique and unusual props and set pieces are all part of the fun with the musical comedy “Nunsense,” continuing its run this weekend at Columbia Center for the Arts. This is a Plays for Non-Profits production, with proceeds going to Providence Hospital Foundation and Music Therapy Program.

Snoopy’s doghouse and Lucy’s psychiatry booth flank the stage in this story about a desperation “let’s put on a show” effort by a group of hapless nuns. One of the sisters sings a song and does dialogue with a ventriloquist dummy created for the show by April Sampson of White Salmon, an artist as well as an actor, most recently seen in “Chicago: the Musical.”
