Heat oven to 375°F. Separate dough into 8 biscuits. Place on ungreased large cookie sheet; press each biscuit to 4 1/2-inch round. Bake 12 to 15 minutes or until golden brown.
2 . Meanwhile, in 12-inch nonstick skillet, cook beef over medium heat 8 to 10 minutes, stirring occasionally, until thoroughly cooked; drain. Stir in sloppy Joe sauce and corn. Reduce heat to medium-low; cook 3 to 5 minutes, stirring occasionally, until hot.
3 . With sharp knife, cut out small triangles from each cheese slice for eyes and nose, and half moon shape for mouth.
4 . Spoon beef mixture evenly onto biscuit rounds. Arrange cheese pieces over beef mixture to look like jack-o'-lanterns. Place bell pepper piece on top of each to look like stem. Bake 3 to 5 minutes longer or until cheese is melted.
