Peel raw shrimp. Set shrimp aside in a bowl, sprinkle with creole seasoning, toss to coat, and return to refrigerator.

Place shrimp shells in a small saucepan, add 2 cups of water, bring to a boil over medium high heat. Reduce heat and simmer for 20 minutes. Pour liquid through a strainer into a bowl. Throw away shells.

While stock is simmering, cook noodles according to package directions, and begin cooking remaining ingredients.

Melt 2 tbs butter in a deep sided skillet over medium heat. Add mushrooms. Cook until they just begin to soften (about 5 minutes). Add zucchini and shrimp. Continue cooking until shrimp is almost done, about 5 minutes more.

Add shrimp stock. Bring to a boil. Let cook uncovered 5 minutes more. Stir in remaining butter until melted and incorporated. Add cooked noodles and toss to coat in sauce. Serve hot. Enjoy!
