Family of Odd Eaters

They were the oddest family and they ate no normal things Before doctoring them up with metal, oil, and whatever nature brings. Cottage cheese could not be eaten without a little bit of sequins blue. How did they swallow those sharp bits, some a different hue? The daughter dipped her French fries in chocolate cake batter, Son ate so many thing made of copper, his teeth were all a smatter. The father ate a bit of wet cat food on his sandwiches with glee. Why the mother ran away from the family is a mystery to me
