As the Chomper, swallow a Goat.
Its name is a portmanteau of "goat," the animal involved in this achievement and "oatmeal," a porridge made from oat grains.
- The Chomper in the icon resembles the one in Plants vs. Zombies 2 rather than the one in the Garden Warfare series.
- It is a pun off of "oatmeal", a type of food made with oats, and "goat", the animal that a Chomper has to swallow to get this achievement
- Also, it is a pun because you are eating and making a meal out of a goat as a Chomper, hence "Goatmeal".
- It is the third Goat-related achievement in Garden Warfare 2, with the other two being You've Goat to Be Kidding Me! and Goat Any Last Words?.
