I would love to walk on the beaches of The Sea of Non-Specificity, see more crabs, possibly collect sand to make sandcastles/sandcastle parts and glass. Maybe even feed a seagull for birdpoo (We have guano and plops, why not seagull poo? Maybe you could feed a seagull something specific and it would allow you to choose someone to poo on? Okay... I digress - seagull poo isn't all that a Glitchian beach has to offer.)
My point is this: Not only is the idea of a beach really awesome, but it's possibilities could be never ending!
