I found these to be pretty interesting. The top picture gives you a tentacle count so you can accurately give your squids/squidsona's an accurate count. But of course, you can be like me and just ignore it or say your squid has mutated extras. (My squidsona Zeek accidentally has more than he should, but in my defense, I didn't have the book yet so I didn't know about it, plus I love his design too much to change it,) but if you want to be accurate and have the info, here it is! I'm not sure what the second photo is. Apologies, I am not fluent in Japanese whatsoever. My guess is that it's either an age chart or the transformation sequence from squid to kid. If it is an age chart, it might be interesting to note that they don't start off as kids or humanized babies. But like I said, I can't be sure. The last one is interesting because it gives us a little insight on the things squiddies eat. Apparently Kelp Dome grows all kinds of strange fruits that are fresh with squids such as blue watermelons and lemons that look like turkeys. They have a picture of other fruits on the top of the page, but like I mentioned in the other post, the book makes it rather difficult to take photos.
