Chop 100 g chocolate coating. Melt the coconut oil in a hot water bath with 1⁄2 cubes. Drain the pineapple. Puree finely with a hand blender. Put the biscuits in a large freezer bag, seal it and roll a pastry roll over them until the biscuits are finely crumbled.
Place in a mixing bowl with pineapple puree and 50 g coconut flakes. Mix in the melted chocolate coating well. Form cherry-sized balls with slightly moistened hands. Chill for about 1 hour.
Put the remaining grated coconut in a deep plate. Chop the rest of the chocolate coating. Melt with the remaining coconut oil in a hot water bath. Dip the balls into the chocolate coating using a praline fork (or wooden skewer).
Drain well and turn immediately in the coconut shavings. Put them on baking paper and let them set in the fridge in about 1 hour.
