In "Flounder!" siblings Haden, Ella Grace, and Walker are spending the day with their grandparents, Nana T and Pop, by the shore, and are begging to check the crab trap and go fishing! The kids playfully tease Nana T until they are on their way to the water. While there, they spot a fish mixed in with the crabs that looks pretty strange - its body is flat, and it has both eyes on the same side of its head! This sparks a discussion on the fish known as the flounder and makes Haden want to go fishing for a big one. Haden experiences an exciting time while fishing that results in help from Pop, but also a new fishing hat, just like he wanted.
"Flounder!" showcases a happy and carefree family who is respectful of themselves and what's around them. The love they have for each other is evident in their actions. "Flounder!" is a moment in time memorialized by Nana T to serve as both a keepsake for her and her family as well as a model for others on how to use what's in nature as a means to learn in a less traditional way than pen and paper. The story contains some mild excitement while pairing as a way of learning.
