I may be (and probably am) entirely wrong, but I THINK that there may be a small error when Mr. Pig is talking to his friend Lion. The English translation says that Lion offers Mr. Pig his stripes, but wouldn't 头发 be referring to the Mane instead of stripes? (Also, lions don't have stripes) 

Otherwise, great work! I'll definitely be using this site as a resource to improve my Mandarin reading!
