The Troll first appeared in May 2007, chained to some pipes beneath a large sidewalk grate near the Arkansas River. He was created by local sculptor Constance Ernatt, stands seven feet tall, and weighs 200 pounds -- although it's difficult to appreciate his size in his underground prison. He is not built like a tank (like other trolls) but is actually kind of spindly, with green skin, a bald head, and big ears. He looks more like a goblin, or maybe an oversized, evil Yoda.
The troll inhabits an abandoned outflow junction formerly used by a nearby energy plant, allowing the city to keep it as an art installation rather than have to pay to dig it up. Morons broke into the troll's lair in 2013, stealing his arm and his bird skull necklace. Constance removed, repaired, and returned him to his lair in April 2014, and Wichita has promised better security to keep the troll safe.
