Preheat the oven to 375 degrees and line a baking sheet with parchment paper.
In a mixing bowl, combine the cream cheese, cheddar cheese, and crumbled bacon until evenly mixed.
Fill each jalapeño half with the cheese and bacon mixture.
Unroll the crescent dough and cut it into thin strips. Wrap the strips around each filled jalapeño to create a mummy look, leaving space for the eyes.
Place the wrapped poppers on the baking sheet and bake for 15 to 18 minutes until the dough is golden.
Remove from the oven and press two olive slices onto each popper for eyes while still warm.
