Answer:
The part of the reading that uses cartoon language is "When he is bored or nervous, time creeps by, literally". This part establishes ideas for the passage of time that occurs at a speed very different from the real world. These ideas are directly suggested, making the reader quickly understand, that the text refers to a playful, unreal world and can even be crazy.
Step-by-step explanation:
As you already know, a cartoon offers a universe, many times, totally different from the real world. This scenario is fanciful, irrreal, exaggerated, overwhelming and often crazy and chaotic, but it portrays a situation that fits totally into this universe.
An example of this can be seen in the question above. When we read that "When he is bored or nervous, time creeps by, literally", we can see that this is a different universe from the real world, which offers us a perfect language to be used in a cartoon. That's because in the real world, time doesn't go according to our state of boredom and nervousness.
