This was the sixth episode of season two to air in the UK, on 10th January, 2007. (edit) Listen Hard: The shark-woman sounds a lot like Kath Soucie. (edit) Jake thought Derceto was the Kelpie; Derceto thought Jake was the Kelpie; in reality, Fu Dog's blind date, "La Betty 42," was the Kelpie, disguised as a French poodle. (edit) Female Magical Creatures that Jake tries to hook Grandpa Lao Shi up with are a Hag, a Werewolf, a Two-headed woman, and a Shark woman. (edit) According to Derceto, Jake has been sent to the principal's office 37 Times!. She even complains that "I even see my secretary less than you!" (edit) We learn that Principal Derceto happened to be an Undercover Mermaid, to catch the Kelpie. (edit) This episode marks the third known love interest Lao Shi has had, with the previous two being Councilor Chang (revealed in "Hong Kong Nights") and Mrs. Hasagawa (Hawaiian woman from the Lilo & Stitch: The Series crossover episode, "Morpholomew"). (edit) Principal Derceto's first name is Dolores. (edit) The mermaid, Silver, from the episode The Hunted appears in this episode once again. (edit) Kari Wahlgren reprises her role of Silver, the aquaphobic mermaid from "The Hunted," and this episode marks the first appearance of Silver's new animation. (edit) Dragon Training Secret 206: Never play matchmaker for your grandfather (edit)

Derceto: Jake! I believe your grandfather sent something with you.
Jake: (Sighs) Yes ma'ma. (Holds out a rose) Till next we meet. A rose to remind you...you are my sweet. (A bunch of kids laugh at him) (edit) Jake: Gotcha! And the catch of the day is...fresh, ugly, Kelpie.
Derceto: What are you talking about!? Your the Kelpie!
Jake: Say what?
Derceto: You can't run forever! I'm not the only mermaid who's after you.
Jake: Mermaid!? Awwww man! (edit) Jake: Woah, rewind and remix. This thing wants to eat me so it can be me!
Silver: He won't actually eat you. He'll just slowly drain your essence with his icy cold bite sending your soul into enternal darkness and leaving your lifeless husk of a body behind. Oh, that's not much better is it?
Fu: Well, I guess it's nice you get to keep your husk. (edit) Fu: Do you guys mind keeping it down? I found me a cute french poodle named LaBetty42, and oh la la, any woman who can make me L-O-L on my P-C 24/7, is A-OK with M-E. (edit) Trixie: (after the Kelpie is defeated) Uh, just so you know, sweetie. I'm gonna need some extra credit for this. (edit) Spud: (holding an aquarium) Why won't you tell me your secrets? In my heart, I'm already one of you! (saying 'glub' multiple times) (edit) (Two-headed woman has shown up for a date with Grandpa.)
Red-haired head ("Sandy"): Hi! So meet to great you! Er...wait...
White-haired head: Great, Sandy! You ruined it again! (edit) (Ms. Derceto and Spud, on Ms. Derceto's back, enter the transport bubble with Kelpie and guards heading back to Atlantis.)
Spud: (Bubble begins submerging) I can't believe it!! I'm really going!! Whee!! (gargling)
Spud: (Pops out of the top of the bubble) Wait! Do over! I breathed in a minnow. (edit) Fu Dog: Now thats what I call squidlock he he he (Nobody laughs and Fu Dog sighes) Nobody gets me. (edit)

Grandpa denying that Derceto is his enemy is very similar to the way Jake refused to believe that Rose was the Huntsgirl in "Ski Trip". (edit) If this episode is correct Principal Derceto has been an undercover mermaid since season one. (edit) In this episode, Professor Rotwood becomes the new principal of Millard Fillmore Middle School, but in "The Doppelganger Gang" (which aired before this episode), it's mentioned he already was the principal. This is because the episodes are aired out of their production order; "Something Fishy This Way Comes" takes place before "The Doppelganger Gang". (edit) Closed captioning misspells Principal Derceto's name as "Dursetto." (edit)

The idea of a mermaid using a wheelchair to hide her identity has also been used in the golden era of Superman magazine, that of his girlfriend Lori Lemaris whom he met during his senior year of college. (edit) The design of Kelpie seems to be very much influenced by the classic design of the similar aquatic monster that terrorized beings in The Creature from the Black Lagoon. (edit) In the credits when Fu is singing the song about principal Derceto, he uses the theme of Shaft just with different lyrics. (edit) The title also refers to a Ray Bradbury book called "Something Wicked This Way Comes." That line is also in Shakespeare's "Macbeth" and was also the tagline for "Harry Potter and the Prisoner of Azkaban." (edit)
