I have never heard the term “noddy” but assume it is a cognate for “nodding off”? That would make sense in context but I wonder if you mean something else by it?
> Noddy being associated with small children's reading has led to "Noddy" being sometimes used as an adjective meaning "petty or trivial" (compare with "Mickey Mouse"), for example, in computer programming: "This simultaneous linear equation subroutine crashes out on the Noddy case when n = 1, but otherwise it works." or "Remember to check all the Noddy cases."
