Guide awaiting review
Wait for Reclamation Rig
The Reclamation Rig construction project must be active and completed for the day before the event begins. Check whether the project is available before proceeding.
Complete the Rig Event
After the Reclamation Rig is built, an event starts. Completing the standard event rewards a 
Box of Assorted Parts, which has a chance to contain the Echoing Oozeling — the drop is not guaranteed.
Activate Hard Mode
To trigger hard mode, use the crafted Super Collider weapon during the event to force all spawning elementals into large orange-red forms. At the end, stronger versions of those mobs will appear. Completing hard mode rewards an 
Irradiated Box of Assorted Parts, which can also contain the Echoing Oozeling.
Claim Your Oozeling
Open whichever box you obtained — the standard or irradiated version — for a chance to receive the Echoing Oozeling. As a cageable pet, it can also be purchased from other players on the Auction House if you prefer to skip the event.
Tips
The Echoing Oozeling is a magic-family pet with a P/B breed, giving it both solid attack power and a large health pool, making it a strong and durable choice in pet battles.
Two pets can drop from the Reclamation Rig event: the Echoing Oozeling from the
Box of Assorted Parts, and the Irradiated Elementaling via the 
Irradiated Undercoat from hard mode.
