This comment is a little late, but I loved the "Foot Pain" poster.

(Me personally, I usually squawk like a sucker-punched chicken when I stub my toe. :!)
Also, forgive me, but I can't resist disgorging another complementary gobbet of trivia.

The mammals in “Stranger from the Mysterious Above” are based on
Ceratogaulus (formerly known as
Epigaulus), the only known horned rodent, which lived in the Miocene epoch, over 40 million years after the last non-avian dinosaurs. Whoops. :blink:
In order to pole climb, you kinda need opposable thumbs. 
Or claws that can dig into whatever the pole is made of. Or adhesive pads or setae on the feet like a tree frog or gecko. Or just hands with a certain degree of grasping capability (mostóif not allómonkeys lack thumbs that oppose the way humans' do).
Ironically,
Hypsilophodon was once believed to be a tree-dwelling dinosaur.
