Who's Where?
From Tardis Wiki, the free Doctor Who reference
Who's Where? was a recurring series of "search-and-find" pages that appeared in Doctor Who Adventures.
Each instalment consisted of a large, double-page illustration of multiple characters interacting and partaking in various activities within a single setting. The reader is tasked with finding a set amount of a particular object hidden within it, with additional challenges also occasionally being given. The words and illustration for each instalment are created by Christopher Cooper.
The segment appeared in the magazine on an irregular basis up to DWM 159, after which it was replaced with the functionally identical Find It! series.
