Prehistoric Farm’s official description advertises Open Sea fishing and diving, taking sea reptile eggs from Sunken Grotto, and teaming up with other players using spears against the giant Mosasaurus. The detailed sea route currently supplied is Kai’s Whirlpool access to Panthalassa and Yara’s Sea Egg/Pacific Shovel progression. Those activities have different goals and should not be merged into one invented combat or egg recipe.
For Yara, Titanium is needed for the Sea Egg shard rocks. Exchange shards at Home for three Sea Eggs of any kind, keep them unhatched, and give Yara the eggs plus one Nessie Fragment. After those objectives, Pacific costs 350,000 Coins. The October 12 complete route uses Level 30+ and Titanium; that is not a separate universal diving requirement. Read the full returns, fragment window and tool conditions.
The official description establishes sneaking into Sunken Grotto to steal sea reptile eggs. It does not supply the exact entrance, access requirement, take control, escape sequence or resulting species. Those specific details are needed for a complete Grotto acquisition walkthrough; the existing activity remains worth distinguishing from fossil conversion at Dr. Ivy and the unhatched eggs used in sea quests. No invented egg odds or guaranteed species is attached to Grotto.
The official cooperative encounter uses other players and spears. It does not give spear price/damage, boss health, attack patterns, spawn schedule or reward quantities. Kai’s guide instead directs a player to a Mosasaurus Skull pickup on Cretaceous through a quest pointer. That task is not proof that defeating the giant encounter is required for Kai’s skull. Prepare the actual Kai hand-in route if Panthalassa access is your goal.
Diving is separately named alongside fishing by the official listing. Its entry control, diving gear, underwater catches and constraints are not supplied in that description. The rod-and-bait instructions from the fishing guide therefore should not be passed off as diving controls. The known Home vendors and Kai’s fish count remain useful for fishing preparation.
For a documented sea purchase, continue to Pacific Shovel; for the different newer key-gated boss reports, use Indoraptor/Raptor X source labels. Neither path invents the missing Grotto, diving or Mosasaurus combat procedure.
The 11 October creator update names Indoraptor as a new boss, says a key is required and mentions a new shovel at a small chance. The creator does not give a numeric chance, damage values or the full key-acquisition route.
Raptor X is separately named as one of the five new dinosaurs in that update. The two names are not treated as interchangeable. The official giant-Mosasaurus spear encounter is another activity; its skull quest is a separate route. Read the dated update and name distinction.

The executable supplied route is Kai’s Panthalassa access: pointer skull pickup/return, fifty actual fish, twelve Devonian shards for three unhatched eggs, then Whirlpool. Yara’s right-of-spawn shop requires Titanium Sea Egg shards exchanged at Home, three unhatched Sea Eggs, one fragment and 350,000 Coins for Pacific. These are not a Sunken Grotto entrance map or a universal diving gate.
The official description names diving, sneaking into Grotto for sea reptile eggs and team spear combat with Mosasaurus. Exact cave entrance, gear/controls, take/escape sequence and rewards are the still-unsupplied parts of those full goals. No sea-area tier order, spawn layout, secret key recipe or new island seed is manufactured. Keep the documented route useful and the separate key-gated boss reports distinct.
This listing contains one named Indoraptor record with the dated key and unspecified shovel-drop report. The cards show each entry’s useful collected fields, source/version conditions and real detail or next-step link. The listing order is a reference arrangement, not an income or rarity tier.
