Place the watermelon, 1 tbsp sugar and lemon juice in a blender and pulse until smooth. Pour into a popsicle mold, filling them 2/3 full. Divide the chocolate chips between the molds and gently disperse within the molds with an extra popsicle stick. Place popsicle sticks into the molds and freeze until frozen solid, 1-2 hours.
Spoon some yogurt on top of each popsicle, leaving room for the honeydew melon layer. Freeze for 1 hour, or until fully frozen.
Place the honeydew melon and sugar in a blender and pulse until smooth. Spoon the mixture onto the popsicles and freeze for 2 hours, or until frozen solid.
Unmold the popsicles by running the popsicle mold under warm water – make sure not to get water INTO the mold! To store, wrap each popsicle in wax paper and place them in a freezer bag. Store in the freezer and enjoy whenever you like!
