The Portrayal of HumansThere is some inconsistency throughout the game as to which humans are drawn like regular humans and which are drawn in the distinctive pigtailed big-eyed silhouette style. But it has become clear that this is dependent on the perspective of the toy the player is dealing with at the time.
How Kroko and Dr Wood Complement Each OtherDr Wood and Kroko both work their way to opposite and yet very much the same positions over the course of their therapy processes. Both of them have something missing. For Kroko, it's a physical object that fills a pocket in his chest when he gains it; for Dr Wood, it's an aspect of life, and his retrieving it is symbolised by the complete loss of his hood, something physical. Both of them have to dive into something dangerous from a great height to get their missing things. Kroko has to go into a pool of water filled with haunting eyes (which, as Fridge Brilliance within Fridge Brilliance, evoke the Eye of Horus) to fetch his hot water bottle from his reflection; Dr Wood has to dive down into a pit of spikes to meet he-doesn't-yet-know-what from a very high icebergian bed that he himself made (which, by the way, was initially floated out to sea, another giant expanse of water). Both of them need to have their bravery worked up gradually. For Kroko, this requires desensitization by one drop of water at a time; in Dr Wood's case it requires a hallucination wherein he is fondled by things he considers alien (which he fought off in an earlier sequence). And finally, both of them get to their happy place by flying. Kroko follows the advice given to him by the motivational tape that told him he was an eagle and flies into the water. Meanwhile: after Dr Wood comes out of his spike-dream, he flaps his arms again, three times, and shakes his head. Then, in turn, after his child-initiation, he does the same thing, looking a lot happier about it. Before and after he confronts his fear, Dr Wood is flying.
