Hey Kendra,

I'm not sure if you are still active on this blog, but first of all I want to say thank you for your work! It really makes practising easier, if you have the pop-up function and a translation and it's much more fun this way.

One minor comment: 
I think the pig suggests with 我用嘴一拱 that it could have dug a hole in the earth with its snout to make the wolf fall down the mountain.

Best wishes!
