How to Get the Grow a Garden Dilophosaurus

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 Dilophosaurus Passive Ability
Grow a Garden Dilophosaurus’ unique passive ability is called Frilled Reptile. Every 13.44 minutes, the Dilophosaurus opens its frills and spits out venom. This venom spreads to 3.52 other random pets. The venom advances their cooldown by 41.29 seconds OR grants them 616.65 XP.

Grow a Garden Dilophosaurus is considered one of the best Primal Egg pets for players focused on pet mutations and leveling. Its ability to advance cooldowns or grant bonus XP to other active pets is crucial for boosting the experience gain of your garden’s best pets, especially with the pet mutations update. This effectively helps you optimize your pet lineup and their efficiency.
