The title and flavortext clues that you need to find the answers that can be followed by the word ball such as BASKETball or MEATball.
From the flavortext, we also get that the mechanic is changing one letter to get from the word clued by each line in the puzzle to one of the answer words.

I wanted to make an easy puzzle because of all the feeders there are in this hunt and I thought this would be a pretty approachable and nice way to make a puzzle relevant to this answer. I'm not the happiest about the RACKET-ROCKET clue but racketball does exist in England and is apparently similar to Squash.
