"Deep sea treasure hunting"

After about 12 minutes of searching a shipwreck a few hundred feet underwater, this lizard's found a chest! Even if it wasn't locked, he knows not to worry about opening it right now, especially as low on breath as he is. Dragging the chest outside, he wraps it in the chain let down from his ship way up at the surface, then holds said chain and notifies his crew through his waterproof radio. They don't understand what he's saying, but he'd told them to expect bubbletalk, and that's enough. The chain starts being pulled up, bringing the lizard and the treasure with it. Can he hold his breath long enough to reach the surface? It's gonna be close...
