P.I.X.A.L. is working on one of them, but it sets on fire, and Lloyd puts it out. The other three are also seen.
Jay's sub car powers down and begins flooding. He tries to break open the cockpit, but to no avail. Luckily, Benthomaar and Cole, in his mini submarine, arrive and save him. Kai and Zane, in their mini submarines, retreat, and they arrive at the Ninjago News Center, where they hide the vehicles.
The mini submarines can travel underwater and fire rockets.
- 71754 Water Dragon (Zane's)
- 71755 Temple of the Endless Sea (Kai's)
- 71756 Hydro Bounty (Lloyd and Cole's)
- Lloyd's mini submarine is the only one that didn't appear in the show.
- This is the first time that several ninja have exactly the same vehicle in the sets, except for different colors.
- In front of the submarines are pairs of the same weapons that the ninja have on their harpoon guns in sets for Season 14.
