Slice your mini watermelon in half. Use a paring knife to slice around the inside edge of the watermelon. Then cut horizonal and vertical lines into the watermelon to create large chunks (like slicing an avocado).
Use a large spoon and scoop out the chunks and place on a parchment lined baking sheet. Freeze the watermelon for 1.5- 2 hours or until fully frozen.
To a blender add your fruit, honey, coconut cream, and the rums. Blend until smooth and thick.
If it's a little too thin for your liking, add some ice or a little more frozen fruit to thicken if needed.
Pour into the watermelon halves and serve with a few pineapple slices and leaves and a sprinkle of chia seeds if desired.
Serve these in glasses instead if you prefer! If you have extra colada in your pitcher, store in the freezer and stir before serving.
