Edited for Syndication: The version that aired on PBS Kids, The Noddy Shop, took the classic episodes and sandwiched them between live action and puppetry segments.
Also, the US version of Make Way For Noddy has the Say It With Noddy segment which teaches Spanish. This segment is absent from the version of the show aired elsewhere.
Keep Circulating the Tapes: While the CGI series have got some fair exposure on DVD, you'll be lucky to find much of Toyland Adventures (though most of the series was released on VHS). And don't even bother looking for the 50s-70s shows.
The Other Marty/The Other Darrin: Noddy between the classic episodes and Make Way for Noddy. Also, between the US and UK dubs, which both uses different talent houses.
Recycled Script: Both Toyland Adventures and Make Way For Noddy have a loose adaptation of the novel story Noddy and Tessie Bear (Noddy loses Tessie Bear's farm goods on his runaway kite, which "rains" on the rest of Toyland).
Same Language Dub: Typical of US/UK televised children shows, Make Way For Noddy has two distinct voice actor sets- one for the UK and one for the US. The US version was voiced by VAs from The Ocean Group. The UK version used BBC talents.
