Combine chia seeds and coconut milk in a bowl. Stir well to prevent clumping and refrigerate for at least 2 hours until it sets to a pudding-like consistency.

Layer chia pudding into the bottom of two glasses. Use a spoon to evenly distribute the pudding for a balanced base that supports the fruit layers above.

Blend frozen raspberries, banana, and additional coconut milk until thick and smooth. Carefully pour this luscious pink layer over the chia pudding, creating a striking contrast.

Mix banana, spinach, kiwis, ice, and coconut milk in a blender until smooth. Gently pour this vibrant green layer on top of the raspberry layer, ensuring colors don't fully mix for a dramatic effect.

Garnish with additional sliced fruit, if desired. Serve immediately or chill for later enjoyment.
