McWalrus is a fast food restaurant chain found in the ships of the Pilkington Navy and on Robert claimed bases. McWalrus's slogan is,"The fastest way to Diabetes". McWalrus's menu shows all the food from Robbaz's Cocking with the Cock series. McWalrus has been renovated and relocated many times aboard both the Pilkington and the Ragnarök.
After the destruction of the Pilkington the Ragnarök is the only other ship in the Pilkington Fleet to house a McWalrus. Once the Ragnarök took to the skies in honor of the Pilkington McWalrus got an upgrade to its grilling system, allowing it to increase the rate of diabetes given to its customers.
