Goldie Seeking

Goldie Seeking is a Known Occurrence in Salmon Run.

Salmonid Field Guide
The following text is quoted from the Salmonid Field Guide.
 * What Happens
 * Large numbers of Gushers will appear in the area.
 * A Goldie will be hiding in one of the Gushers.
 * You can shoot the Gusher to make it erupt, but chances are a regular salmonid will pop out instead of a Goldie.
 * How to Get Golden Eggs
 * The Goldie lurking in one of the Gushers will drop loads of Golden Eggs when hit with ink.
 * Advice from Mr. Grizz
 * Spread out, and find that Goldie FAST.
 * When you find the Goldie, call your buddies over and let loose with all your firepower!
 * The Gushers emit light when you hit them--the brighter the light, the closer you are to that glorious Goldie.
 * Supplementary Information
 * Salmonids obtained the technology to create Gushers through trade with Octarians.
 * The Goldie loses scales when hit, so it's able to move faster the more you damage it!

Basic Tips

 * When the Goldie is discovered, rolling into it with the Dynamo Roller can cause it to drop a large quantity of Golden Eggs at once.
 * Other rollers work, too, but have lower damage per second.
 * The Goldie has 6500 HP and drops a golden egg for every 500 HP damage sustained, and its HP slowly regenerates over time.
 * Opening as few Gushers as possible is recommended, as Salmonids continue to spawn from the incorrect ones until the Goldie is discovered.
 * The Gushers also spout higher if they have a connection to the Goldie's hiding place (see Graph Theory section).
 * Even though the next Goldie location is randomized, there is still a way to optimize it so players always know exactly where it is:
 * Every map has starting point(s) at low or mid tide. Players can determine where the Goldie is if the gusher(s) are low or high, then go different ways to find the exact location.
 * If players find a high Gusher, they can say "This way!" whereas if they find a low Gusher, they can say "Booyah!"
 * Furthermore, players can say "Booyah!" if the Goldie is going through the basket, allowing crewmates to reposition.
 * Try chasing the Goldie near the Egg Basket because if a Goldie is being chased away from the basket, Snatchers may steal the trail of Golden Eggs.

Gusher Graphs
Gusher height is actually not based on physical distance, but instead graph theory. The Gushers themselves are the nodes of this graph, with invisible programmed connections between them called edges. Gushers are neighbors if they are connected by one of these such edges. If a Gusher hides a Goldie, its neighbors will spout high when opened; all other Gushers spout low. Be wary of Gushers that are neighbors to all the others on the map. These universal neighbors, in this case universal Gushers, will never spout low, meaning if they don't hide the Goldie, they're not going to help you find it.

Trivia

 * It is possible to splat the Goldie by depleting its HP. If this happens, any opened Gushers will close and reset, and another Goldie will hide in a different Gusher.
 * Taking off 2500 HP will shrink it down to medium size. Taking off 2000 more HP will shrink it down to the smallest size. Finally, depleting 2000 more HP from it while it is in that state will finish it off.
 * In other words, the Goldie drops a minimum of 13 golden eggs (6500/500) until it gets splatted and drops 3 golden eggs, resulting in a minimum total of 16 golden eggs. However, it is possible to have it drop 17 or more golden eggs in one turn if it is allowed to recuperate HP over time.
