• Pearl: Redrop of one random symbol type, keeping any feature symbols locked. Redrops continue as long as matching symbols or Wilds land.


• Squid: Moves to random positions and generates additional Wilds.


• Starfish: Clears symbols in a random direction and adds a multiplier to the last position affected. This sequence repeats until the Starfish becomes a wild.

• Regular Wilds: Substitute for any standard symbol to help form clusters.
