* SinisterStingray: Aku briefly takes the form of a giant monstrous manta ray.

* AndYourRewardIsEdible: To make up for their treachery and thank him for saving their lives, the Triseraquins give Jack some of their sushi, to which he happily eats later on as he's traveling.

* EasilyForgiven: Jack easily forgives the Triseraquins for selling him out to Aku and nearly getting him killed, as after all, few can resist Aku's wiles and trickery.

* FishPeople: What the Triceraquins are.
* GiantSquid: Aku takes on this form to fight the Triseraquins' military when they try to fight him.
* IDidWhatIHadToDo: The Triseraquins didn't like tricking Jack and making him a sacrificial offering to Aku, even hesitating going through with the trap. Their reasoning was to have Aku raise their city back to the surface, as well as their livelihoods.
* ILied: The Triseraquins capture Jack for Aku after he promises to remerge their city from underwater. Quite expectedly, after they capture Jack, he gloats he has "changed his mind", giving them reason to free Jack as revenge.

* NoCelebritiesWereHarmed: One of the Triceraquins has a voice similar to Music/RingoStarr and is even named "Ringo" in the credits. It helps that he's voiced by Jess Harnell, who used the same Ringo impression for [[WesternAnimation/{{Animaniacs}} Wacko Warner]]. Guinness and Connery likewise sound like and are named in reference to Alec Guinness and Sean Connery.

* VillainBall: After capturing Jack in a bubble, Aku decides to, instead of crushing him instantly, to leave a ''teeny'' crack in his bubble so he can watch Jack slowly drown. Of course Aku also decides to double cross the Tricerquins ''before'' Jack is dead, leading them to rescue Jack and set up his downfall.

* EatenAlive: After being shipwrecked, Jack is swallowed whole by a huge fish. He still gets a good view of the outside world thanks to the fish's back being a transparent dome, and he manages to manipulate its nerve ganglia to get it where he wants it to go.

* AtlantisIsBoring: Played with; the Triseraquins complain that they haven't received any visitors since their city was sunk, as they seem to be the only people under the sea. However, the underwater realm itself is lushly portrayed as beautiful and full of strange life (there's a rather nice sequence during Jack’s trip devoted to showing just how much weird stuff there is down there), and there's certainly plenty going on to keep Jack busy in Oceanus itself.

** The fisherman telling the story of the Triseraquins is dismissed by the other patrons of the restaurant, especially after he says their treasure is a time machine. Jack is the only one who believes it, for obvious reasons. The fact that only he believes the man suggests the story was made specifically for him.
** The Triseraquins already know Jack is about to ask for the time machine at dinner before he's about to asking for it, almost like they knew he would. After they tell him he can use it, Guinness tells Jack the time machine needs adjustments before it's ready. He has a very notable pause prior to saying the world "details", hinting he's not being honest about it.

* AtlantisIsBoring: While it's somewhat played with in that the Triseraquins complain that they haven't received any visitors since their city was sunk, as they seem to be the only people under the sea, the underwater realm itself is lushly portrayed as beautiful and full of strange life (there's a rather nice sequence during Jack’s trip devoted to showing just how much weird stuff there is down there), and there's certainly plenty going on to keep Jack busy in Oceanus itself.

* FishPeople: What thr Triceraquins are.

* EasilyForgiven: Jack easily forgives the Triseraquins for selling him out to Aku and nearly getting him killed, as after all few can resist Aku's wiles and trickery.

* UnderwaterCity: Oceanus, the city of the Triseraquins, built as a system of waterproof domes on top of high-tech towers. It used to be a CityOnTheWater instead, but Aku banished them beneath the ocean to where their city is now. It returns to the surface by the end of the episode.

Jack is informed by a fisherman about the underwater city of Oceanus, which has a time machine, so Jack dives into the darks depths of the ocean, where he encounters the Triceraquins, the amphibious denizens of Oceanus whose city was sunken by Aku. There, the Triceraquins agree to let Jack use the time machine, but their real plans are far more sinister.

* GiantSquid: Aku takes on this form to fight the Triseraquins’ military when they try to fight him.
* OrganicTechnology: The Triseraquins make heavy use of this -- their vehicles all appear to be highly modified fish, and even the time machine [[spoiler:or trap, technically]] and a good portion of their city are organic in nature.
* TimeMachine: Rumors of one such machine are the reason why Jack seeks out Oceanus in the first place, so that he can return to the past and prevent Aku from taking over the world. [[spoiler:Sadly, it doesn't exist -- it was all just a trick to lure Jack into a trap.]]
