Fill a shaker with ice, then add Midori, Malibu, banana liqueur, pineapple juice, and heavy cream.
Shake vigorously for about 15 seconds to chill and mix everything together.
Strain into a chilled glass filled with ice.
If desired, top with whipped cream for extra creaminess.
Garnish with fresh mint and a green candy frog on the rim for the ultimate swampy look.
Place fairy lights behind or under the glass for a magical glowing effect.
