Matschie's Tree Kangaroo do look like they are naturally smiling. Sort of in the way a teddy bear works. Quokka, I would say they are known for full on laughing as opposed to just smiling.Also can someone please explain to me why there’s any discussion whatsoever about the smile drink being a tree kangaroo? I don’t get it. All of the other drink associations are very on the nose. This has to be an animal known for smiling. I can at least humor the crested macaque suggestion even though I’ve very confident it’s still wrong, but why it would point towards a tree kangaroo is just absolutely behind me.
Also tree kangaroos are cute enough they make you smile.
