Trivia

 * This was advertised as and shown on TV channel guides as "The Teen Titans Go! and Powerpuff Girls Completely Organic Crossover Special" (the longest episode title of the series), but the actual title was "TTG v PPG" with the abbreviation of two show titles. This is ironically one of the shortest episode titles of the series.

Trivia (Teen Titans Go!)

 * This is the fourth crossover of this series. The first three were "The Best Robin", "Let's Get Serious" and "Truth, Justice, and What?", but this is the first crossover with the other characters' current designs.
 * This is the seventh episode to have the title be different from when it was advertised.
 * This is the second episode with the show's title dropped in its title. The first time was "The Teen Titans Go Easter Holiday Classic".
 * This was aired one year after "Operation Tin Man" and Cyborg's birthday.
 * This was Tom Kenny's third role as The Powerpuff Girls' Narrator of this series. His first role was Flex from "Birds", Mumbo Jumbo and Magic God from "Real Magic".
 * This is the first episode to be TV Y7-FV.
 * Music from "Uncle Jokes" and "Brian" was reused.

Trivia (The Powerpuff Girls)

 * Animation from The Powerpuff Girls Rule! was reused.
 * This is the first crossover episode that begins without the city skyline. The Narrator is heard saying "The secret lab of the most sinister of simians, Mojo Jojo. Up to no good, no doubt".
 * The Powerpuff Girls and Mojo Jojo appeared in their 2016 counterparts. This is the first crossover special to feature the familar and well-known 2008 design of the Girls and Mojo (design from The Powerpuff Girls Rule!). They were designed by current character design artist Chris Battle (even though he's previously worked in the original Powerpuff Girls series).
 * Mojo Jojo even made his own army of monkeys in a similar way to the 2002 film The Powerpuff Girls Movie, which is actually based on the original 1998 series.
 * This is the first crossover The Powerpuff Girls has had.
 * Tara Strong who voices Raven in the series had originally voiced Bubbles from the original 1998 series.

Continuity

 * This is the third Cartoon Network crossover, the first was "The Grim Adventures of the KND", a crossover for The Grim Adventures of Billy and Mandy and Codename: Kids Next Door, and the second was "Say Uncle", a crossover for Steven Universe and Uncle Grandpa.

Continuity (Teen Titans Go!)

 * This is the 42nd time that Raven is unhooded in the series.


 * This is the second time when the abbreviated word "v" was tied in the title. The first was "Batman v Teen Titans: Dark Injustice".
 * This is the 20th time Beast Boy doesn't use any animal transformations.

Continuity (The Powerpuff Girls)

 * When the Titans treat the Girls as "babies", the same thing happened to the students from Midway Elementary School from "The Wrinklegruff Gals".

References (Teen Titans Go!)

 * Raven saying she's "Chico" is a reference to The Marx Brothers.
 * Coincidentally, all Cs is a reference to all Bs on The Powerpuff Girls.

References (The Powerpuff Girls)

 * This is the first crossover episode that the pulsating letter "T" outro screen was a reference of the original Powerpuff Girls series pulsating heart outro screen including the falling stars. The Narrator is heard saying "And so, once again the day is saved, no thanks to...the Teen Titans! Seriously, what's wrong with those guys?".

Errors

 * TBA

Running Gags

 * Starfire, Robin, and Raven mocking Bubbles, Blossom, and Buttercup by calling them "babies".
 * Robin telling the PPG Narrator to say what he is doing out loud.
