In a mixing bowl, beat the softened cream cheese with an electric mixer until smooth.
Gradually add the powdered sugar and vanilla extract, mixing until well combined.
Gently fold in the whipped topping until the mixture is light and fluffy.
In a separate bowl, brush both sides of each tortilla with melted butter.
Heat a skillet over medium heat and cook each tortilla for about 1-2 minutes on each side until golden and slightly crispy.
Remove the tortillas from the skillet and let them cool slightly.
Spoon the cheesecake mixture into each tortilla, folding them like tacos.
Sprinkle the additional Fruity Pebbles on top of the filled tacos.
Drizzle with chocolate syrup if desired.
Serve immediately or refrigerate for up to 30 minutes to chill before serving.
