What we are making this activity?

This is a word ladder puzzle. The goal of this puzzle is to transform the word "BAT" into the word "CAT" using only 3-letter words. Each consecutive word must share 2 letters with the previous word, and only 1 letter can be changed at a time.

For instance:

BAT -> BIT

BIT -> CIT

CIT -> CAT

Thus, solving the puzzle involves identifying these 3-letter words that form a sequence between the starting word and the target word, where only 1 letter is modified at a time.
