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.
Fridge Brilliance: General Parvo's hatred of the Road Rovers and the reason he's always coughing makes perfect sense when you see his helmet removed and realize that he has cat ears, making him part cat and that he was coughing up hairballs the whole time.
"Funny Aneurysm" Moment: The episode with werewolves opens with Princess Diana and Prince Charles finalizing details of their divorce just before werewolves attack them. Following Diana's death, they had to cut all references to this.
Genius Bonus: General Parvo is named after the parvovirus, which has a contagious canine strain with a high mortality rate.
The Woobie: Sport from the episode "The Dog Who Knew Too Much". He was dognapped from his master and forced into being a mole for Parvo. Poor guy could really use a big hug.
Luka the blind boy from the episode "Gold and Retrievers", who was separated from his seeing eye dog.
Exile could really, REALLY use a hug in the werewolf episode. He even begs to be locked up because he thinks he's a dangerous werewolf but it turns out Colleen was the one who was the ACTUAL werewolf.
Muzzle in the time-travel episode. Stolen from his owner, subjected to an experimental version of the transdogmafier, driven insane — and then having to spend most of his time strapped down and muzzled so that he doesn't bite The Master who happens to be his original owner, Professor Sheperd. Poor Scout.
