In a large mixing bowl, combine cooked crab meat, shrimp, softened cream cheese, and shredded cheddar cheese. Add finely chopped green onions, garlic powder, Old Bay seasoning, salt, and pepper. Mix until creamy.

Lay a small flour tortilla flat, spoon 2-3 tablespoons of filling into the center. Fold sides over filling, then roll from the bottom to create a sealed bomb shape.

In a skillet, pour enough oil to cover the bottom about 1-2 inches deep, heat over medium-high flame. To test, drop a small piece of tortilla in; it should sizzle.

Carefully place the filled tortilla bombs into hot oil, fry for 3-4 minutes until golden brown, flipping halfway through. Remove and drain on a paper towel.

Serve warm alongside dipping sauces like zesty salsa or creamy avocado dip.
