Trade Pets in the DNA Machine

Trading Pets with Graham can provide many items, including a Primal Egg. Hence, take note that this isn't a guaranteed way to acquire the titular zygote.

- Press "E" to interact with him.
- Next, hold the Pet that you wish to trade and click on the "Take this Pet" option.
- The NPC will take the pet and put it in the DNA machine beside him. This will start a timer.
- Once the clock hits 0, claim the reward, possibly a Primal Egg, from the DNA Machine.
