!!This episode provides examples of

* AlmostKiss: Between Casey and April
* AmusementPark: Most of the plot takes place on Coney Island.
* AnnoyingYoungerSibling: The Turtles (sans Leo) are so annoying to April that she is relieved to finally see another human, Casey.
** Mikey keeps flying around the lair in his {{hoverboard}}.
** Raph then tries to grab the board and tosses Mike off right on top of April.
** [[RuleOfThree Then]] Don jumps into a pool splashing April in the process. When April complains about getting sewer water all over her, Don assures her that it is sea water from the bay. April isn't comforted by this news.
* ArtisticLicensePhysics: Don turns the roller coaster into an electromagnetic pulse emitter, which emits a ''ball'' of EMP that soars ''along the tracks'' like a train car, and ''only'' takes out Nano and not any of the other tech in the immediate vicinity
* BittersweetEnding: Poor Nano is deactivated--lamenting not having a family. Meanwhile, the Turtles give April a missing treasure so she can use the reward money to rebuild her shop.
* CharacterizationMarchesOn: In the prior episode, Harry actually did come to care for Nano and regretted his apparent death. This time, he just sees Nano as a means to an end and wants nothing else to do with him.
* CrazyJealousGuy: While April and Casey insist that they are [[NotADate not on a date]], which was true, once Don takes April with him, Casey gets mad.
-->'''Casey:''' Hey, that sneaky little green nerd just stole my date!
* DelayingAction: Raph, Mikey and Leo fight Nano to give Don time to set up his EMP emitter.
* FullNameUltimatum: April gets drenched by the pool water After Don dives in, he simply explains it is not sewer water, but sea water, then jumps in again.
-->'''April:''' Donatello! don't you— ''(He dives and splashes her again)'' Ohh! [[SarcasmMode This day just keeps getting better and better!]]
* FromBadToWorse: During Nano's last tantrum, the Turtles try to talk to him to calm him down. Nano brings up his memory files of their last encounter and proceeds to get even angrier.
* HourglassPlot: In the previous episode, Leo was annoyed by April, who is living with the Turtles. Here, April is annoyed by [[AnnoyingYoungerSibling the Turtles' antics.]]
* {{Jerkass}}: Once Harry has got his stolen loot back, he doesn't want Nano around any more.
* {{Nanomachines}}: Nano.
* NotADate: [[HeIsNotMyBoyfriend April and Casey keep insisting to Splinter and the turtles that their late-night jaunt to Coney Island is this]]. Technically speaking, it wasn't--it was actually just some repair job that Casey invited April to tag along with him on (and to help him out). But it quickly goes into a date-like mode, and after Donny whisks away April to help him in defeating Nano, Casey gets mad and says, "That sneaky little green nerd just stole my date!"
* PlatonicKissing: In the end when the Turtles give the stolen loot to April and Don tells April she won't have to be [[AnnoyingYoungerSibling around them]] anymore, she kisses him on the cheek and tells him that [[FamilyOfChoice they are family]] and she will see them all the time.[[note]]Peter Laird, who was heavily involved with the development of the show [[http://peterlairdstmntblog.blogspot.com/2011/07/blast-from-past-375-feb-3-2004-more.html disliked human-turtle romance and forbade the writers from shipping them]] and even Kevin Munroe, who worked with Laird on [[WesternAnimation/{{TMNT}} the 2007 movie]] [[https://animatedviews.com/2007/director-kevin-munroe-on-tmnt/ said that one of Laird's very strict rules was to not have any human-turtle romance]], meaning April and the Turtles' relationship in this show was always meant to be platonic/familial.[[/note]]
* SympathyForTheDevil: Nano kept trying to kill them and was generally dangerous, but after learning that he only wanted a family of his own, the Turtles openly feel bad for him.
* TookALevelInJerkass: Harry who seemed to have genuine affection for Nano last time here does not seem to care about him beyond using him to help him escape and get his loot.
* TroubledChild: Nano takes it a step further than last time. Having the mind of a child, he willingly enters the role of the child in the old-fashioned show he watched and wants to build a family with Harry as "Daddy" and Dr. Marion Richards as "Mommy." And, of course, when he doesn't get his way, his tantrums are quite dangerous.
