Prepare a shaker full of ice then add the Raspberry vodka, Banana schnapps (I use 99 Bananas), Triple sec, Cran-Raspberry juice, and Lime juice. Shake vigorously then pour into a chillled martini glass. Add the Tonic water to taste. Add a few raspberries to the bottom of the glass for garnish.

Note: I use regular cranberry juice with this, too. It just depends what I have on hand.
