Trivia:
- At the beginning of the episode, the old man who is listening the radio hear news about Ben defeating the Dimension 12's robots. This could means the return of this guys in another future episode, where we could see them directly in action. Maybe with Computron reconstructed.
- According to Rook, the Kraken's dribble and digestive fluids smell worst than Stinkfly.
- Xylene is mentioned by Magister Patelliday while he and Max are fighting. It seems the three of them (and someone else which I couldn't here) spent a weekend in Casiopea in their youth.
- Rath's feline nature is remarked in this episode, as when they are falling from the waterfall, Rath goes nuts because he hates water. As it's said that cats hate water.
- Captain Kork's ship has a skull form, possibly as reference to the Jolly Roger.
Errors:
- In the closing credits, Stinkfly appears between the casting; but it didn't appear in the episode, Rook simply made a short mention about him.
Data about the villains:
+ The Mechancer are the robotic pirate minions of Captain Kork. They are robots with crab forms. Even their names reflect that: Combining "Mechanical" and "Cancer" (the Zodiac sign with a crab as a symbol).
+ The design of Captain Kork makes a lot of references to Disney's movies about Pirates:
- His beard is similar to the famous Edward Teach, a.k.a. Blackbeard. Blackbeard appeared as the main antagonist of the movie "Pirates of the Caribbean: On Stranger Tides". And just like Captain Korkin did in this episode, Blackbeard was capturing ships in the movie, shrunk them with voodoo magic and put them inside bottles.
- Having a creature named "Kraken" as his pet and "fish guardian" can be a reference to Davy Jones, the main antagonist in "Pirates of the Caribbean: Dead Ma's Chest". Davy Jones also had a "Kraken" in this film. And just like Davy Jones, Captain Kork also has a "stick leg" and a hook (actually a crab's pincer).
- Captain Kork's hook and name can also be a reference to Captain Hook, the villain of "Peter Pan". He even makes a comment that his hook is "a tribute to the traditions".
- At the end of the episode, Captain Kork laugh of one of Rook's lame jokes with "Yohohoho". That's an obvious reference to the theme song from teh attraction "Pirates of the Caribbean" is Disneyland Parks.
