Traffic Light Cooler

Into pilsner glass filled with ice cubes, first pour the melon liqueur, then the tequila, to create a green layer. Add sour mix. Slowly pour orange juice against side of glass to create the yellow layer. Add a few more ice cubes, if needed. Carefully float the sloe gin on top for the red layer. Garnish with a cherry and lemon and lime wheels. Stir just before drinking.
