Start by mixing the chia seeds, nut milk, coconut milk, coconut yogurt, blue spirulina, and maple syrup together in a bowl until everything is well blended.
Allow the mixture to rest for about 5 minutes, then stir again to break up any clumps and ensure a smooth texture.
Transfer the pudding into a container or individual portions, cover, and place in the fridge to chill for at least 2 hours.
When ready to serve, scoop the pudding into small bowls.
In a separate bowl, blend the Greek style vegan yogurt with matcha powder, then carefully spoon small dollops onto the pudding to create shapes resembling countries, adding a playful earth-themed touch.
