The Mosasaurus is one of the most impressive and sought-after creatures in Raise Animals. Known for its colossal size and unique abilities, obtaining this aquatic behemoth is a major goal for many players. However, the path to getting one is not straightforward and relies on a specific process of biome unlocking and egg fusion.
This guide will walk you through the exact steps, spawn chances, and strategies you need to successfully add a Mosasaurus to your collection.
What is the Mosasaurus in Raise Animals?
Before embarking on the journey, it’s important to know what makes the Mosasaurus special. It is one of the largest and rarest animals in the game.
Size & Growth: It starts giant at age 10, covering a significant portion of land, and continues to grow until it reaches age 100.
Stats: It has relatively low Speed (5-18) and Health (2 hearts).
Special Ability – Tidal Rampage: Every 30 seconds, the Mosasaurus enters a rampage mode for 15 seconds. During this time, it destroys obstacles and consumes nearby animals. Each obstacle destroyed grants a small speed boost and slows down enemies in the surrounding area.
Step-by-Step Guide to Getting Mosasaurus
Getting the Mosasaurus is a multi-step process that requires both in-game currency and patience.
Step 1: Unlock the CRETATERRA Biome
The Mosasaurus cannot be found in the standard starting areas. You must first unlock its exclusive biome.
Go to the Play menu.
Select Maps.
Find and purchase the CRETATERRA biome. This costs approximately 5 million in-game currency.
The CRETATERRA biome is the only place where you can find the eggs necessary to fuse for a Mosasaurus.
Step 2: Find the Right Eggs
Once you are in the CRETATERRA biome, you need to wait for an Egg Fall event.
The chance for an Egg Fall to occur is 20%.
Each Egg Fall event drops three eggs.
However, each of these eggs only has a 30% chance to be a real, usable egg. The other 70% of the time, it will be a Ruby.
This step is heavily reliant on luck, so it may take some time to collect a few usable eggs.
Step 3: Fuse Eggs to Tier 5
This is the most critical part of the process. You must use the Egg Fusion feature in the Incubation Pod to increase the tier of your eggs. Higher tiers have a chance to yield rarer animals.
The fusion outcome for tier 5 eggs in the CRETATERRA biome is as follows:
Carnotaurus: 40% Spawn Chance
Spinosaurus: 45% Spawn Chance
Mosasaurus: 15% Spawn Chance
As you can see, the Mosasaurus has the lowest individual spawn chance, making it the rarest outcome from a tier 5 fusion.
Step 4: Hatch the Egg
After a successful fusion that results in a Mosasaurus egg, you can proceed to hatch it.
Go to the Hatch Egg menu.
The standard hatch time for a Mosasaurus egg is 2 hours.
You can choose to wait or use in-game currency to instantly complete the hatching process.
Upon hatching, your Mosasaurus will already be massive and will continue to grow as it ages.
Tips to Increase Your Success Chance
While the process is luck-based, you can optimize your strategy.
Focus on Tier 4 and 5 Fusions: Only high-tier fusions in the CRETATERRA biome can produce a Mosasaurus. Don’t waste time on lower-tier eggs.
Save DNA: Use stored DNA from other animals to speed up the fusion process, allowing you to attempt more fusions in less time.
Patience is Key: With a 15% spawn chance per tier 5 fusion, you will likely need several attempts. Don’t get discouraged if you get a Carnotaurus or Spinosaurus first.
Frequently Asked Questions (FAQ)
Q: What is the spawn chance for Mosasaurus in Raise Animals?
A: The spawn chance for a Mosasaurus is 15% when you successfully perform an Egg Fusion that results in a tier 5 egg within the CRETATERRA biome.
Q: How do you do egg fusion in Raise Animals?
A: Go to the Incubation Pod in your game. Place two eggs of the same tier into the pod to fuse them into one egg of a higher tier. This is essential for reaching tier 5, which is required for the Mosasaurus.
Q: Can I get Mosasaurus without the CRETATERRA biome?
A: No. The CRETATERRA biome is mandatory. It is the only map where the eggs capable of fusing into a Mosasaurus can be found.
Q: Why is my Mosasaurus so slow?
A: The Mosasaurus is designed with low base speed (5-18) as a trade-off for its immense size and powerful Tidal Rampage ability. Its speed is not its primary feature.
Conclusion
Obtaining the Mosasaurus in Raise Animals is a true test of patience and resource management. The journey involves unlocking the expensive CRETATERRA biome, patiently collecting eggs from random events, and mastering the egg fusion system to target a rare 15% chance. While the process can be lengthy, the reward—a constantly growing, obstacle-destroying leviathan—is a unique and prestigious addition to any player’s collection. Focus on high-tier fusions, manage your resources wisely, and good luck on your hunt
