You know the Big 5 and the Little 5. You may have even heard of the ‘Ugly 5’ (of which only one is actually ugly), but have you heard of the ‘Impossible 5?’  Nope, neither had I, but it’s a thing. Apparently.

This morning I came across these tracks, belonging to a member of this ‘Impossible 5.’ And it’s one who I’d really really love to see. I’ve seen it just once, at night, 7 years ago and only got a glimpse of its back before it disappeared into the night.

Can you tell who it is by looking at this track?

Or this one?

Maybe it helps to have a look at the book…

What do y’all think?
