Grelch is a food delicacy created by Gaston the gremlin in the cartoon show episode "The Grumpy Gremlin". It consists of wild onions and garlic relish, and produces a powerful foul odor when it's being cooked. Gaston haunted Peewit with the smell of grelch after accidentally cutting down the tree that was his home, and would not depart until Peewit found a suitable replacement tree where he could cook his grelch in peace. Ultimately Gaston settled in the forest by the Purple Falls, which was home to a dragon that seemed like a menace, but proved to be very friendly with Gaston as he served his new pet grelch.
