Start by preparing the Gelatin. In a small bowl, add ½ cup of water and sprinkle unflavored gelatin over it. Let it sit for about 5 minutes to allow the gelatin to bloom (absorb the water).
Heat the condensed milk, coconut cream and coconut milk together in a small saucepan over medium heat.
Add the bloomed gelatin to the milk mixture and whisk it together until everything is dissolved. Turn off the heat and let it cool.
In a separate bowl, add crushed pineapple and mix in 1 tablespoon of pineapple syrup from the can.
Next, add the cooled milk mixture to the pineapple and mix it together.
Scoop out some of the mixtures into individual serving cups or ramekins and chill it in the refrigerator for at least 4 hours or overnight.
Before serving, top each mousse with maraschino cherries and grated coconut.
