What's up with the frog and the word game? I seem to make out "Hello friend!" at the beginning and then I'm lost about how to decipher his message and how to answer (?) him. In the screenshot I also can make out "please" as well as "and", I think. If anyone has a hint who already has figured it out, that would be great :) 
Thanks for taking the time to answer :) Hmm, maybe I will stumble upon one of the features in-game that allow me to decipher the frog language easier. I'm also curious about the frog that has a bookshelf on its boat like the guy that can make one of the crew mates smarter but you can't interact with the bookshelf frog. For the first time, I have a frog on my boat because of the cat goddess but that hasn't made communicating with the frogs easier :D
