The Spinosaurus is a Divine-tier pet in Roblox: Grow a Garden, considered the most powerful companion to hatch after the Pet Mutations update. It was added to the game on July 12th, 2025, as part of this update.
How to Get the Grow a Garden Spinosaurus
Primal Egg
The primary way to obtain the Spinosaurus is by hatching a Primal Egg. The Spinosaurus has a 0.5% chance of hatching from a Primal Egg, making it the rarest pet from this egg. Primal Eggs take four hours and ten minutes to hatch.
You can acquire Primal Eggs through several methods:
Crafting Primwal Eggs
You first need to unlock the ability to craft these eggs by upgrading the DNA Machine four times, which requires giving a total of 280 KG of Prehistoric Plants to Barry. Once unlocked, head to the crafting table (located near the Pre-historic quest stall or Blaire NPC in the central area).
The crafting recipe for a Primal Egg is: 1x Dinosaur Egg, 1x Bone Blossom, and 5,500,000 Sheckles. Crafting a Primal Egg takes thirty minutes.
Trading Pets in the DNA Machine
You need to upgrade the DNA Machine by speaking with Barry. Giving him 40 KG of Prehistoric Plants will make Primal Eggs have a chance to appear. To unlock Primal Eggs in the reward pool from trading, the machine must be upgraded three times. The “green dinosaur variant” of the DNA machine signifies max level.
Interact with the Graham NPC (located behind the Dinosaur Eggs stall). Give Graham your non-dinosaur pets. The DNA machine will then process the trade, and you have a chance to receive a Primal Egg (or a Dinosaur Egg or even a Primal Egg pet directly). This method is based on probability.
Buying from the In-Game Shop
You can purchase Premium Primal Eggs using Robux from the Limited-Time Shop. Costs are 149 Robux for one, 429 Robux for three, and 1,269 Robux for ten.
Buying Premium Primal Eggs offers benefits: the hatch time is greatly reduced to just 30 seconds (compared to 4 hours and 10 minutes for crafted eggs). It also grants better chances of obtaining higher rarity pets and a chance to get another Primal Egg.
Note that a rainbow variant of dinosaurs (except Spinosaurus) can be obtained via this method, and it may be a limited-time offer.
Grow a Garden Spinosaurus Passive Ability
Grow a Garden Spinosaurus’ ability is called Food Chain. Every 19:07m, the Spinosaurus will devour a random mutation from 4.27 fruits in your garden. Afterward, it will roar and spread those mutations to 1 random fruit in your garden. It prioritizes applying mutations to favorited fruit.
This ability allows you to get a single crop with an insane number of potentially rare mutations like Celestial, Shocked, or Aurora, which can skyrocket its resale value. It is considered the most powerful pet for stacking mutations. For example, if it devours Rainbow, Gold, and Windstruck mutations from different plants, it will transfer all of them to one random fruit.
You can further boost its ability with pet mutations. It is also a great pet to have working while you are away from the game (AFK) due to its cooldown-based ability. Having multiple Grow a Garden Spinosaurus pets can increase the chance of this effect occurring.
