The Tale of Benthomaar is the one hundred and seventy-second episode of Ninjago: Masters of Spinjitzu, and the eighth episode of season fourteen.
Spoiler warning: Plot or ending details follow.
Benthomaar shares with his new friends the tale of how he came to be adopted by King Trimaar, having been separated from his birth parents in circumstances he cannot remember. Trimaar and Prince Kalmaar came across him as he was being attacked by monstrous eels, with Trimaar driving off the eels over Kalmaar's objections. Trimaar gave Benthomaar his name and raised him like his own son. Unfortunately, Kalmaar regarded his adopted sibling-and everyone else not of royal blood-with contempt, being obsessed with finding a way to awaken Wojira.
One day, Kalmaar discovered a forbidden scroll detailing the location of the Temple of Wojira in the Tartarus Trench, and confronted his father about it. Trimaar, appalled that he would seek out such knowledge, ordered Kalmaar to pursue it no further. However, Kalmaar refused to accept this, and decided to try and reach the temple-or rather, let Benthomaar try it for him to insure it was possible to survive. Feigning admiration of his adopted brother and a desire to reconcile, Kalmaar convinced Benthomaar to swim into the trench.
When Benthomaar expressed his doubts, Kalmaar played upon Benthomaar's desire to be accepted by him to get him to enter the dangerous trench. Benthomaar succeeded in finding them a safe route to the temple, even driving off one of the same type of eels that had threatened him as a child. Sadly, Kalmaar then ordered Benthomaar to leave, revealing that he had merely used Benthomaar for his own purposes, and making Bentho realize that Kalmaar would never love him. Having heard the tale, the crew of the Hydro Bounty gladly welcome Benthomaar as a friend, and become more determined than ever to thwart Kalmaar's ambitions.
Spoilers end here.
King Trimaar's reference to "Underseabiscuit" is a parody of Seabiscuit, a real-world racing horse from the mid-to-late 1930s.
