"Not sure. Never tested it. Faster than humans." Eric said as he eyed the wound, skin slowly growing back. "This might take maybe an hour?" He shrugged, unbothered by it, by the process. He was making a friend; sacrificing a bit of skin to do that didn't bother him at all. And he was getting a tattoo out of it, albeit a temporary tattoo, a tattoo that would remind him of his mother. She wasn't dead, he was just very far away from her, from his roots, from his bloom and his children, and so having something that reminded him of them would be very comforting.
He canted his head to the side as Chandra continued to speak. Meaning in the meaningless; Eric rolled that over in his mind. "I am the one who is gone." He told him. "My mother, my children, they are all still on the ocean floor. Maybe they are doing things to remember me at the same time as I am doing this to remember them." Maybe that should have made Eric sad but, instead, it was comforting, as comforting as this temporary tattoo would be.
Peering down as Chandra started to mix the pink, Eric watched. "Is lighter than that. Light pink, not hot pink." He directed, and when it was as close to his mother's ethereal glow as it could get without actually glowing, Eric nodded. "Is good. And I want the design to be simple. Just two small scales, one pink, one blue, right here." He pointed to his bare chest, where his heart was. "How long will it last?"
