Bring a large pot of water to a boil. Cook the egg noodles until they are tender and fully cooked. Drain the noodles well and toss them with garlic oil to prevent sticking. (No matter what type of noodle you choose, be sure to carefully read the package instructions for cooking time and method).
In the same pot with boiling water, blanch the vegetables for about 30 seconds or until they become soft. Remove all the boiling water. Add the cooked noodles, crab balls, fish balls, and vegetables to the pot, and mix them well with fish sauce, sugar, and chili flakes.
