Preheat oven to 300°F (150°C) and line a baking sheet with parchment paper or a silicone baking mat.
Arrange the mini pretzel twists in a single layer on the prepared baking sheet, spaced approximately 1 inch apart.
Place one chocolate-covered caramel candy in the center of each pretzel twist.
Bake for 3 to 5 minutes, or until the candies are soft to the touch but have not lost their shape or melted completely.
Remove the baking sheet from the oven and immediately press one pecan half firmly into the center of each softened candy to flatten it.
Allow the turtles to cool completely on the baking sheet at room temperature for 30 minutes, or refrigerate for 15 minutes until the chocolate is set.
