File stops petting over their head, to Alt's slight dismay, but Alt has to continue walking forward, anyway. "Let's get buildin', hmm?" Walking over to the area he had set out, he gauges the size. 49 square feet for the sandcastle... extravagant. Perfect! "File, you can head out. We'll be needing a lot. Fry, we'll be starting here. The base of the castle is a square, 7 feet long by 7 feel wide. There will not be rooms, as this build will be solid, but there are areas with different elevations." They toss the notepad at her. "Use this as reference. The back of this will likely be to the sea."
File's head dips in a nod, and it shoots over to the ocean with surprising speed, getting sucked into the waters just like before. White tentacles emerge from the water for a moment before disappearing beneath the surface. Time to feast!
Caim cackles, cheering him on.
