Spawn GameObject Above and Below GameObject

I want to have it so when he shoots and hits a fruit, it will spawn a split picture of the fruit above the watermelon and below it. It will destroy the fruit, but I want the split picture to spawn where ever the fruit is because the fruit falls and you try to hit the fruit. So to kinda sum it up, I want it to spawn an object above and below where ever the watermelon is when I shoot. Thank you in advance.
