<human>: things that make a cartoon popular include people who always complain about things, like poor quality or bad construction, or things like scary underground caves or scary mazes that look like actual caves but are actually underground structures with hilarious names like " the haunted mansion " or " the road runner ". these things make cartoons popular, but they always feature poor people trying to make various improvements to their inventions and then getting purged by every other invention. the underground caves were different from normal caves because they had different levels of difficulty and different features such as staircases or large rock formations. these features along with the road runner shorts made this collection of fantastic shorts into a fantastic volume.
<bot>: I'm sorry. I don't understand. Can you repeat that in another way?
