Where can I find the credits for these?

Where can I find the credits for these?

I'd like to use the Pumpking sprite in my Late Fall Game Jam project as the final boss, seeing as the game's caled Pumpkin Quest. As I remembered seeing him on the LPC page, I went there and found him under the Assets Directory tab, but there's no attribution information listed, could someone help me track it down? :)
