Most of our Rhino dealings are done with bells on and big feet. But there are Missions when We need to be invisible, undetectable. That’s how Missions work.
Happily, Rhinos have a fine method for Sneaking. We keep our eyes scrunched shut. Very tight. We can almost always navigate by nose or ear, both fine-tuned. If desperate, We peek, but only a teensy slit.
The scrunched eye makes Us Invisible! If We can’t see, We reason that We can’t be seen by anybody else. Showing once again that Logic is helpful in the Wild.
