A “Trick or Treat on the Waterfront” party Sunday will feature what’s becoming a rare event, a visit from longtime Seattle TV clown J.P. Patches.

Chris Wedes, 79, who plays Patches, recently canceled most of his appearances after being diagnosed with blood cancer. Wedes undergoes dialysis several times a week and said he’s been told the cancer can be controlled but not cured. “I’m optimistic. I actually feel pretty good,” Wedes said, also keeping a KCTS Channel 9 fundraiser on his schedule in December.

At the Sunday event, J.P. and Ketchikan the Animal Man will be at the Seattle Aquarium from noon to 1:30 p.m.

Other activities at the daylong party for kids include trick-or-treating at waterfront businesses, music, pumpkin-carving and a raid by the Seafair Pirates. Details: www.seattleaquarium.org.

Meanwhile, a committee of Patches fans (www.jppatches.com) has selected Sultan artist Kevin Pettelle to build a statue of J.P. and his sidekick, Gertrude, in Fremont. The group has raised $60,000 toward its goal of $150,000.
