[Secret Squirrel]

Thanks for the confirmation, Prime Blue, and for looking over the translation.

12 - Into the Door

I wonder if "Through the Door" is what they are really saying here.

15 - Beddy-Bye

I agree.

18 - The Underground of the Giant Tree

Nothing sounds smooth here, but how about "Underground in the Giant Tree." It's another valid translation for no, where [Place] + no == in [Place] instead of "of".

33 - Way Home

I'd go with making them both "The Way Home". To me, "way" sounds awkward without "the".
