Explanation: it's the most intense part of the whole story and if you stop right there and it leaves you off of cliffhanger then you definitely know it's the climax
Got this from google: noun. the highest or most intense point in the development or resolution of something; culmination: His career reached its climax when he was elected president. (in a dramatic or literary work) a decisive moment that is of maximum intensity or is a major turning point in a plot.
from this definition, you can see this is the climax because you're thinking to yourself, "What will the wolf do next? Wow, that was a close one, what now?"
