Fill a cocktail shaker with ice.

Add pineapple juice, melon liqueur, and coconut rum to the shaker.

Cover the shaker and shake vigorously until the outside is frosted.

Strain the mixture into a chilled rocks glass.

Carefully pour the raspberry liqueur into the glass, allowing it to settle at the bottom.

Gently float the Jägermeister on top by pouring it over the back of a spoon or by using a pourer.
