[Not wanting to get more sand than was unavoidable on him, Nagisa has refrained from taking a seat on the beach. Instead, he removed his socks and shoes so that he could stand on the shoreline, letting the tide lap at his bare feet and idly flexing his toes into the wet sand. He'd allowed his attention to wander a bit as he stared out at the horizon, and as such, hadn't immediately realized Jataro was talking to him. He picked up on it quickly enough, however, turning his attention to his friend.]

Hm? [What is he rambling about now? Sand worms? Sand snakes? It's not until he catches sight of the sand sculpture that everything finally clicks. He looks suddenly indignant, face slightly flushed as he folds his arms over his chest and spluttering slightly when he speaks.]

O-of course I'd know it's not a real snake. [Give him some credit here, Jataro. He's not Masaru!] And I am not afraid of worms, I just don't like them. Th-There's a difference!!

[Ah, so that's the insinuation that really bothered him. Not the idea that he might not be smart enough to tell the difference between a sand snake and a sand snake.]
