The Penguin works well for learners who already understand English comfortably and want more challenging listening practice. Following the story requires attention, so language difficulty is not the only challenge here. Learners will hear plenty of useful natural English, but some lines may still require a second listen. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 80 words per minute. The Penguin works best for learners around B2/C1 who are ready for a more complex story.
