You can’t think of building sandcastles unless the sand is wet and so you need a lot of water to build something like this in Poctoy white sand beach. 
For once, the rainshower that pours now and then this December season might give you a good excuse to stay out drenched and play with sand and water. Then you might find yourself shaping and carving the damp sand in no time at all - pounding it, pounding it till you get a glimpse of what you have in mind.
When evening comes and you are still at it, you’d want to put candles all over your sandcastle to bring romance and delight to your spur of the moment creation - before the stray dogs or cats destroy it. Like humans do if you are not looking.
