You’ll want to use the Grow a Garden DNA Machine to obtain Dinosaur pets before they become extinct again! I’m only joking, but soon, they will become unobtainable, so that’s sort of the same thing. Our guide explains how it works and what Dinosaur pets you can get.

Enter the Prehistoric Era and play Grow a Garden on Roblox. If you want to keep up to date with what’s going on, we have a Grow A Garden Update Guide.

Grow a Garden DNA Machine Guide

The DNA machine was introduced in the Prehistoric Update. This is only available until the 12th of July, 2025.

How Does The DNA Machine Work?

In the middle of the map, you will find the Prehistoric Update. On one side is the Quest side, where you complete various quests to get rewards. Then there is the DNA Machine, with a small dinosaur sitting beside it.

The DNA Machine, also known as the Pet Mutator, is a machine that mutates any pet into dinosaur eggs. Once you insert a pet, it takes one hour for it to become mutated. They will then convert into 1-4 eggs.

However, there is a small chance that the pet you insert will turn into a dinosaur pet instead. This depends on the type of pet you hand into the machine. The rarer the pet you give, the higher the chance of getting a dinosaur pet.

Dinosaur Egg

So, what’s inside a Dinosaur Egg? Below is everything you can get, the chances, and the abilities it has.
