These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Foe Yay/Stalker with a Crush: Odlaw apparently spends 24/7 stalking Wally by peering through his windows and following him everywhere he goes, having no life outside this. He seems to do this off camera as well, as in one episode, the camera comes up behind him spying on Wally and the narrator asks him to get out of the way, to which Odlaw replies, "Oh. I didn't know you were filming today."
That One Level: "The Fantastic Journey" has a rare non-video game example (though the book does have its own game adaptation) with the Land of Wallies. You have to find Wally in a world that's filled with them and the only clue you've got is that he's missing a shoe.
