In a blender, blend the strawberries, watermelon, lime juice together. Taste, and add a little maple syrup if you feel it needs it (some watermelon is sweeter than others). Pour into popsicle moldes, about 2/3 of the way up. Freeze at least 2 hours. Once slushy/firm enough, add the sticks. This is best when there are no covers on your sticks. If you only sticks with a cover, you might want to only make the pink layer.
Pour a little bit of vanilla-flavored plant milk on top of each popsicle around the stick, and freeze again.
Blend up the ingredients for the green layer, and pour a little bit on top of each popsicle. Enjoy the rest as a green smoothie.
Once completely frozen, run the mold under hot water, slide them out, and enjoy!
