The Elephant and Piggie series has a genius ability to address societal issues in a subtle, non-performative way. Ableism/inclusiveness in "Can I Play Too?", cultural insensitivity in "I really like slop", hypochondria (maybe even medical misinformation?) in "pigs make me sneeze".

Also a huge fan of the gentle odor to organized labor that is Click Clack Moo

Ode! Not odor!
