Spread the peanut butter and jelly on the inside of each slice of bread. Put the slices together to form a sandwich. Using a sharp knife, start at the center top crust of the sandwich and slice off the crust in a curve to make the side of the spaceship. Repeat with the other side. Cut off the crust on the bottom in a straight line. Place the sandwich on the base of a bento box or on a plate.
Place three blueberries in a line on top of the spaceship sandwich base. Place the rest of the blueberries in a small cup on a different level of the bento box on next to the plate.
Slice of a piece of the apple about 1/2 inch thick and the length of the base of the sandwich. Trim the ends to angle outward. Dip the cut edges in lemon juice and place at the base of the sandwich. Cut out wings from more slices of apple, dip in lemon juice, and place on both sides of the sandwich. Slice any extra apple, dip in lemon juice, and serve alongside the spaceship.
Deeply hull the strawberries and slice top to bottom. Arrange 3-4 below the apple base with the tips pointed toward the sandwich. Serve the rest of the strawberries alongside the spaceship. Sprinkle some granola around the edges of the sandwich.
Sprinkle more granola on another level of the bento box if the spaceship level is filled. Peel the carrot and cut into thin strips. Arrange a few over the granola and serve the rest in a small cup alongside the sandwich. Cut a 2 ounce block of cheese into thin slices. Cut out stars using a small star cutter and arrange over the granola and strips of carrot. Add your favorite crackers with the extra cups of berries and other ingredients and serve.
