Sinbad wasn't sure when he fell asleep on the return from Crocell's dungeon, though it was probably after downing half of the contents in his flask. But it was hard to resist the call; he was left to his lonesome without the other generals, just him and his thoughts and his bags of treasure. While they weren't exactly the most luxurious thing to lay back against, it made for a decent enough pillow to rest his head on. Add some alcohol to the mix and the general tiredness one experiences after capturing a Dungeon, and you have the recipe for a short, well-deserved nap.
Since he was asleep, he never noticed the black vines that crept out. He didn't even kick out a leg when they wrapped around his wrist and dragged both him and his treasure into plummeting darkness. The only thing his unconscious self noticed was how suddenly cramped he felt, but it was easily remedied by settling on his side and tucking his knees closer to his abdomen.
What did wake up the king was a combination of two things: a door opening and closing rather loudly, and a man groaning "what the fuck". Very blearily, Sinbad rubbed at his eyes with an overly dramatic yawn followed by him stretching out comfortably. His fist bumped against a tile wall, as did his feet on porcelain. Only then did he realize that the dungeon had dumped him in someone's restroom, and in a cramped bathtub at that. It was strangely cold as well?
He was cold because he didn't have any clothes on, none save his metal vessels and a leaf. That would probably explain why the short, blue-haired man looked very pissed and very flustered. Naked and lost, Sinbad rose from the undignified position and wore his best smile in hopes that it would smooth over any issues that this would undoubtedly cause. "I'm sorry for my state of dress, I'm not sure where my clothes have disappeared to." Couldn't have been a thief if he still had his metal vessels; what sort of thief steals one's underwear, anyways? "I'm not sure where I am either. What country is this and how far is it from Sindria?"
