Boil 1 cup of water in a pan on the stovetop. Once the water is boiling, pour in peach jello and mix well until the powder is dissolved. 

Pour in 1 cup pineapple mango vodka and mix well. Pour into each plastic portion cup making sure they are they are evenly portioned. Place lids on top of each portion cup and place in refrigerator for about 2 hours or until firm. 

When ready to serve, cut pineapple slices in half and garnish each jello shot with a half slice of pineapple. Can also add a cute pineapple paper straw to each cup for show. Consume within 30 minutes and store remaining leftovers in the fridge.
