I had(technically still have) this story idea similar to Nemo in Dreamland, but I never really wrote the story out. What has sorta happened is I've doodled pictures of the story itself, somewhat like a picture book, and the idea has stuck with me that way. Anyhow, I used this IF's word of the week as an excuse to sketch the rabbit character from my story once again.
I don't think that's "earth." I didn't use a reference.
