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.
YMMV: Aaahh!!! Real Monsters
Accidental Innuendo: The episode "Monsters Are Real" has Ickis freak out because a human photographs him. What's odd is that he describes it as a human "flashing" him, which takes on rather risque implications when taken out of context.
Cargo Ship: Ickis falls for a Judy doll in the episode "Blind Love, Monster Love"
"We're the cutest monsters you've ever seen, we are joyful and jolly and never mean!"
Hilarious in Hindsight: People who've seen this cartoon along with Monsters Inc. might get the idea that both the cartoon and the film have similar plot settings since both involve monsters who need to scare in order to collect energy for their society. Come Monsters University, the setting is even more similar to the cartoon as it involves monsters going to school in order to learn how to scare. Mike and Sulley even fill out roles similar to two of the three main characters of the cartoon. A super studious and hardworking student that relies heavily on books, and another student who is generally lazy but pressured with living up to the family legacy of being the best scarers.
