Poe, a raven-morph enemy found beginning on level 68 in the Snowflake forest has the same hopping walk as the macaws.
But he has less reason to be joyful.
Poe is a lone bird in a land of mammals. Wally the walrus, Chompsy the monster -- these species are all furry and distinctly non-avian. Poes live a lonely life in a community of hairballs, overseen by a bigfoot.
So, when we kill Poe, we can think "hey, they were miserable," and be glad for Our Great and Powerful Mercy.
