This puzzle is a meta puzzle that combines the answers to the four previous puzzles to create another answer. Each of the four types of pinball obstacles correspond to one of the four previous puzzles, and the number of that obstacles indexes into that puzzle's answer to produce a single letter. The pink obstacle is a disc from "Discs of Tron."
Play some pinball! Each of the four balls bounces down the obstacles to create a word. The flavor text gives four clues, one for each of the words.
Each of the balls starts bouncing from a different letter and always proceeds to the letter that is either directly to the left or right below it. The final answer is a word that can come after each of the four words you create.
The final answer is also the word resulting from the leftover letters not used for the other four words.
"(I was born) ready" is a clue for the word BABY. This is the only clue that's a pun; the rest of them are more straightforward.
The answer to the clue "(late-night) show" starts at the very top of the obstacles. The remaining words both start with the letter "S."
