Even though every single other Llamas with Hats-related thing I've encountered with them has Loki as Carl (and why not? It's terrifyingly, hilariously fitting XD), having the role switched and Thor being Carl for once is both creative, and fantastic XD
I love Loki's "I AM NOT AMUSED" expression here. It's a delightful, classic sibling look of "Why did I ever think you were supposed to be the mature one here?"
Ok that's funny and creepy at the same time XD ... and i still don't like the idea of Thor being unworthy (i don't like him in comics and toons but is kinda weird... also Chris' version is so cute :,D)
