The Trash Wheel Fan Fest is scheduled for Oct. 20 from 7 p.m. to 10 p.m. at Peabody Heights Brewery and will benefit the initiative to make the harbor safe for swimming and fishing, the release states. The event will feature performance pieces, songs and artwork inspired by Mr. Trash Wheel, his intellectual Canton counterpart Professor Trash Wheel, and Captain Trash Wheel, the gender-neutral new addition to the garbage-gobbling family in Masonville Cove.
