I can be bothered.
That being the case, reverse the Listen and Spot ranks for the giant weresloth?
That would be fine, or go for Listen +7, Spot +4 to make the gap significant. I haven't seen any theorizing on Mylodon senses, but it feels more plausible they have much better hearing than sight - like a wild boar or tapir, which are also forest/jungle herbivores.
