Adaptation Displacement: Subverted. People know about the books, but tend to forget Noddy was on TV well before the 90s rolled around. Need proof? Here is the Title Sequence for a Noddy programme in 1975, and here is the full episode from The Further Adventures of Noddy c. 1972.
Ship Tease: Any moment when Noddy and Tessie are seen together. Especially in the stop-motion series.
Special Effects Failure: Being made in the early 2000s, some of the CGI animation in Make Way For Noddy hasn't aged that well.
Likewise, the low budget of PBS' The Noddy Shop tends to rear it's ugly head in the live action segments, where They Just Didn't Care if the chroma key is done properly or not. Apparently some of the live-action filler, namely those that involve the "goblins", are filmed in front of a blue screen and chroma-keyed onto photographed backgrounds to save costs.
Somewhat averted with the CGI series, since the goblins are far more mischievous and have wreaked much more havoc than in the older series.
The CGI series is dumbed down from the stop motion cartoon however, with more Edutainment Show qualities and many of the cast's Jerk Ass qualities being downplayed. And apparently it has gotten worse with the second CGI series, Noddy in Toyland.
Viewer Gender Confusion: Noddy is actually a BOY! He's probably mistaken for a girl because of his eyelashes and being voiced by a girl. Big Ears... well... not so much...
Martha Monkey can be mistaken as a boy due to the way she dresses. She did wear a pink bow in Toyland Adventures and the books. But since this isn't present in Make Way For Noddy this can cause some viewers to confused her gender.
Wangst: An episode of the CGI series has Tessie despondent for several days due to a balloon she owned popping. She doesn't recover until Noddy gives her several dozen more. Being a Moe, she still makes it sort of adorable however.
Values Dissonance: Before Sly and Gobbo came into the Noddy series in the 70's, there were four black faced dolls called "The Gollies" who would cause mischief as well as not only taking away Noddy's car but including his clothes and hat!◊ (They were eventually redrawn as goblins). In an article made to celebrate Noddy's 40th anniversary, Blyton's daughter stated that the Golliwogs won't make a comeback in the series for obvious reasons similar can be said for Gilbert Golly who was a naughty school girl that would later get replaced by Martha Monkey. However there was one Gollywog that wasn't mean named Mr Golly who previously owned Toy Town Garage who got removed in the early 80's for reasons unexplained.
