* AdoredByTheNetwork: ''Putt Putt Saves the Zoo'' is the game in the series with the most re-releases. Nimbus only heightened its adoration; on top of the fact that it was the first one they released, it clearly is their favorite, having more publicity than the others as well as having an interactive book based on it written by them.
* {{Blooper}}: Putt-Putt's eyebrows are strangely missing on the box art for ''Putt-Putt Saves the Zoo''. This was corrected for the 1999 version.
* ChildrenVoicingChildren:
** Putt-Putt's first voice actor Jason Ellefson was a child when he voiced the character. He retired from the role after ''Travels Through Time'', as his voice was maturing too much for him to continue doing the voice.
** All of the baby animals are also voiced by child actors in ''Putt-Putt Saves the Zoo''.
* CowboyBebopAtHisComputer: The credits in the help file for ''Putt-Putt & Fatty Bear's Activity Pack'' incorrectly list The Fat Man as the game's music composer. The game's musical score is completely recycled from ''Putt-Putt Joins the Parade'', which was ''actually'' done by Tom [=McMail=]. This could have ended up happening due to confusion, as ''Activity Pack'' was sandwiched between two games in the series that were composed by The Fat Man (''Moon'' and ''Zoo'').
* CrossDressingVoices: The latter two of Putt-Putt's three voices, Creator/NancyCartwright and Michelle Thorson. In addition, the UK dubs of ''Travels Through Time'' and ''Enters the Race'' has Putt-Putt being voiced by Lisa Jacobs.
* DevelopmentGag: A clickpoint in the Medieval era in ''Travels Through Time'' causes a moose to appear, in reference to a bizarre and morbid un-joke told by the birds in ''Zoo'' that can only be played as an EasterEgg by messing with the game's settings file. It even has a chance of quoting the joke's punchline!
* DummiedOut: Each game has [[https://tcrf.net/Category:Putt-Putt_series quite a few]], usually accessed by messing around with the INI files in the game. From unused clickpoints and {{Creator In Joke}}s to scenes clearly made to blow off steam.
** ''Dog on a Stick'' has an unused kitchen environment taking place in a [[MacroZone large sink]].
** ''Saves the Zoo'' contains an unused animation where if Putt-Putt eats ten or more servings of cotton candy from Chuck Wagon, he will [[VomitIndiscretionShot vomit it out]], and then Pep will hop out and lick it up.
* MarthDebutedInSmashBros: Because the first two games had few translations, major characters from them such as Smokey and Rover technically debuted in their later appearances' translations.
* NoExportForYou: ''Putt-Putt Joins the Parade'' and ''Putt-Putt Goes to the Moon'' had very few translations.
* TheOtherDarrin:
** In the first four games, Putt-Putt was originally voiced by Jason Ellefson. For ''Enters the Race'' and ''Joins the Circus'', Creator/NancyCartwright took over due to Ellefson aging out of the role. In ''Pep's Birthday Surprise'', the character was voiced by Michelle Thorson.
** Clarence and Gert sound different in ''Goes to the Moon'' than they do in ''Joins the Parade''.
* RecycledScript: ''Pep's Birthday Surprise'' is essentially ''VideoGame/FattyBear'', [[JustForFun/RecycledInSpace but with Putt-Putt]]. Both games involve getting things set up for a birthday party and collecting items to bake and decorate a cake.
* ScrewedByTheLawyers: [[https://law.justia.com/cases/federal/district-courts/FSupp/870/285/1648288/ Almost happened]]. When ''Parade'' was originally released, Humongous tried to get it distributed via Electronic Arts for the 3DO port. This upset Creator/LucasArts who felt it had violated their agreement on the SCUMM engine distribution rights. Had [=LucasArts=] won the suit, Humongous probably wouldn't have gone anywhere past one game; mercifully, the court ruled in favor of Humongous, and the rest is history.
* ThrowItIn: The "I haven't written this verse yet" line in "Welcome To The Zoo" wasn't just a gag. George "The Fat Man" Sanger actually ''hadn't'' written the proper verse yet when it came time to record the vocals, but Ron Gilbert loved it when he heard it and insisted to leave it in that way.
* WhatCouldHaveBeen:
** ''Pep's Birthday Surprise'' had quite a few things that didn't make the final cut:
*** An Apple Orchard mini-game, which would have been accessible from Torvil Tractor's farm and allowed Putt-Putt to continue bringing apples to Mr. Baldini[[note]]mentioned in one of the {{Debug Room}}s and in DummiedOut data[[/note]]
*** Marvin the Marvelous's Confirmation card being separate from the Party Bag[[note]]seen in one of the {{Debug Room}}s[[/note]]
*** A Decorations area and/or mini-game, which would have been accessible from the interior of the Party Store[[note]]mentioned in one of the {{Debug Room}}s[[/note]]
*** Another clickpoint animation for the left light at the Fire Station, removed because Leah (Verre?) didn't like it[[note]]mentioned in DummiedOut data[[/note]]
*** The Party Box being separate from the Party Bag[[note]]seen in one of the {{Debug Room}}s[[/note]]
** There were plans for an animated TV show by Lancit Media Entertainment, but this never mentioned again after the initial announcement.
* WorkingTitle:
** ''Putt-Putt Travels Through Time'''s working title was ''Putt-Putt's Adventure Through Time''.
** ''Putt-Putt: Pep's Birthday Surprise'''s working title was ''Putt VII''.
