Fridge Brilliance
- When Doc opens up toys' chests during surgery, it's revealed they have hearts, "something shown in Doc's Vitruvian Bear picture in her home clinic," but not lungs. But toys with damaged hearts, such as Stanley the rabbit-lion, have breathing difficulties. The hearts of toys, unlike human hearts, also function like lungs. This is why toys don't have lungs—they don't need them.
- Doc's term for stuffing loss is "stuffanemia", which is spelled like "stuff + anemia". Anemia is a lack of something that our body needs (red blood cells), and without it, we become weak and listless. When a toy is missing stuffing, they become floppy and useless, and stuffing is found throughout a toy's body the way blood is found throughout a human's. So stuffing leakage in a toy is indeed similar to anemia.
- Episodes focusing on Wicked King that have other toys in focus actually play a very important role in his Character Development:
- "Kirby and the King"; the episode that Wicked King and Sir Kirby got stuck together, is what started it. As Wicked King only played as a villain until this episode, he never had a chance to properly socialize with the others and they only saw that side of him, but since he was stuck to someone, he really had no choice but to work together with Sir Kirby and thus showing he is more than the villain every one (thinks) they know. Sir Kirby also acted as a Positive Friend Influence and inadvertently helped him become friendlier with others.
- "Wicked King and the Mean Queen"; Wicked King never really had common ground with others and did not had to share either. This episode introduced a Distaff Counterpart of Wicked King, someone who he can relate to, and now had to share his royal authority. This becomes even more brilliant as it was DOC who brought Queen Amina home. Doc has brought toys to life before bringing them home and she could have done the same to Queen Amina. If so, then it would make more sense why the coin-searching game was in play; to help Wicked King see he and Queen Amina are not so different.
- "There's a King in your Tummy"; Wicked King likes to play tricks on others without a second thought since there is no long-term consequence. But being swallowed by Serpent Sam (he didn't do it on purpose but still), can cause him to have second thoughts about tricking people because it was a consequence of his actions, specifically Sam not being able to spray, and he slipped in the pool and got swallowed up by him.
- " Sproingo Boingo Takes the Leap"; Wicked King has made quick, rash decisions for his own benefit, not caring what happens as long as he gets what he wants. But here, one of those decisions is what caused Sproingo to get hurt. He then had a My God, What Have I Done, and realize he needs to think about how his ideas can affect others.
- "A Cure for a King"; Wicked King spends a lot of time taking things that aren't his, but now he has been robbed of something precious to him and nearly GIVING UP BEING KING. What's more, Queen Amina has been teasing him about his situation, just like he would tease others when he took their belongings. He now knows what it's like to have something you love taken away from you and someone taunting you about it. In other words, it is A Taste Of His Own Medicine teaching him humility.
Fridge Horror
- "Gulpy, Gulpy Gators" features Gustave the Gator. Gustave is also the name of an infamous Burundan crocodile with a ravenous taste for human flesh.
- It's explicitly stated that no time passes in the real world while Doc is in McStuffinsville. So is she eating and sleeping there as well, while also maintaining a normal life in the real world? Seems like she'd kind of have to in order to stay sane.
- In "It's a Hard Doc Life," she actually has to be ordered back home by the toys after suffering from overwork.
- Doc can command toys to go inanimate, or "stuffed" as she puts it, and it's implied that they lose consciousness then. Imagine being able to pass out on command!
- Doc's ability to bring the toys to life, and the ability to make them inanimate again, comes from her magical stethoscope. While Doc is not the sort of person who would abuse that power for malicious purposes, imagine what could happen if someone with more insidious intentions towards the toys ever got their hands on the stethoscope...
