The background sound is "BGSOUND", played continuously.
Sinking:
When the ship hits an iceberg, the "Sinking" animation (Sink1-Sink7) plays, as well as the "ICEHIT" sound.
Icebergs:
Can you put in more hazards (icebergs) - I'd say around five. They should be much slower than the dinos or burgers, seeming to drift. Is it easy to 'switch off' the AI? I'd prefer non-intelligent icebergs that don't follow you around, but just float randomly. But if this would take too much time, then we'll have to live with smart chunks of ice.
