Thornax Stew was a failed dish served at Mcdonalds. Ehrye made it out of some cleaning supplies, Vezok's poop, and a weird spiky ball he found at a retirement home for old glatorian. He tried serving it, but the only person who would taste it was the Matoran Nui, since he needed something to wash down Turaga Dume. It ended up giving him parasites (presumably from Vezok's poop), and he ended up sueing Le-Metru (the used car salesman city once sponsored by Geico) to blow off steam. Ehrye still is trying to serve it, but has multiple lawsuits against him, and will presumably be arrested if the toa ever stop being lazy and decide to go after him.
