“I am proud to say it is one of the most sophisticated vessels I have designed, and is practically unsinkable.”

The Hydro Bounty is a submarine that P.I.X.A.L. built, and used by the ninja to navigate through the Endless Sea.


Prior to Seabound

Years ago, P.I.X.A.L. worked on the Hydro Bounty.

The Call of the Deep

After realizing that a mysterious power signal was responsible for the disturbance of the marine life and Nya's powers, P.I.X.A.L. and Wu brought up the Hydro Bounty and the ninja agreed to use it to explore the Tartarus Trench.


The ninja used the Hydro Bounty to dive deep into the Endless Sea. The ninja ventured around the Hydro Bounty, giving glimpses of the many rooms. They approached the Tartarus Trench and were attacked by sea creatures, causing the Bounty to lose power and start to flood.

Five Thousand Fathoms Down

In the ship, the ninja are getting desperate to find a way to get the ship afloat, they come to the conclusion that they should track the energy bursts with Nya and Maya as the elected.

The Wrath of Kalmaar

Zane, P.I.X.A.L., Jay and Lloyd continued to find ways to get the ship afloat to save Nya and Maya. In a desperate attempt, Jay charges the battery with his powers, already knowing the consequences. In the end, he comes out fine and they start tracking the Masters of Water.

Long Live the King

After saving Nya and Maya, the ninja were surrounded by Maaray Guards and are escorted to Merlopia.

Escape from Merlopia

After fighting their way through Guards, the ninja get to the Bounty and escape from Merlopia.

The Tale of Benthomaar

The Storm Amulet

The ninja were in the ship traveling to the Island of the Keepers. To avoid being struck by the storm belt, they go underwater. When they arrive, they surface once more and speak to the Keepers, telling them of the coming danger. They shortly find out that the amulet they have is a fake and get to the Bounty. They warn Cole about the situation, however Kalmaar appears and damages the ship before leaving for Ninjago City.

Riddle of the Sphinx

The ninja were on the Bounty as Nya blamed herself for allowing Kalmaar to get away, fearing the destruction of Ninjago City. However, Benthomaar tells her of how Masters of Water can control sea life. Although doubtful, Nya gives it a try and manages to succeed.

Master of the Sea

Benthomaar tells the ninja about the Battle of Nine Days and Lloyd hopes that the other ninja have stopped Kalmaar. Eventually they make it to Ninjago and fight the Maaray Guards at the Hydro Bounty.

  • The Hydro Bounty is the second vehicle based on the Destiny's Bounty, but adapted to a specific environment. The first was the Land Bounty.
    • Chronologically, the Hydro Bounty is the first while the Land Bounty was the second.
  • According to Tommy Andreasen, it was built sometime after Season 7, because since then P.I.X.A.L. had a physical body.[5]
  • It was originally called the Sword of the Sea.[6] and the Destiny's Typhoon.[7]
  • In the sets, it can hold two mini submarines and the hull of the ship can transform into a mech. Both features are not present in the show.
