Dave comes from the Dave the Diver crossover, and it costs nothing. He arrives once your Sushi Bar reaches level 15 and you have wakened him. See the Blue Hole for how.

The game calls his upgrade screen iDiver. It has six parts:

  • Dive Time sets how long a dive lasts.
  • Max Depth sets how deep he can go.
  • Attack sets how hard he hits a fish.
  • Materials sets how often a fish drops loot.
  • Highest Rarity sets the rarest fish he can catch.
  • Speed sets how fast he swims.

Each level costs Gold, and some also cost loot that Dave finds on his dives. The last level of a part is free of cost because there is nothing past it.

The loot Dave finds on his dives is listed under Dave’s loot, with where each item drops and what needs it.
