As Raz stood in the water, the level being up to his shoulders, the currents started to go under his scales and as they did, the water after Raz gained a soft hue if rusty metal , and then he dunked his head under and moved it around, the water getting it clean too.
By the time Raz was done, his scales gave a rich ebony shine, almost making him blend in with the water if not for his red underbelly.
Raz moved back to the shore and tried to climb up, but the mud there was too much and he couldn't. If Zaida were to feel Raz, she'd feel that he is very cold to the touch and slightly shivering.
