The text for reaching BEst friend with Ella and Fish Felreed are switched. Ella says she will give you pigs, but she actually gives a cat, and Fish says she will give you her cat, but she gives you the pigs.
I can confirm this. The text that occurs upon reaching 'best friend' (not the letter you get in the mail) is backwards Fish mentions the cat, while Ella talks about sending pigs. It's minor but it bugged me a bit.
