My shells, let me show you them.
Shells are cool, but these kids are basically obsessed with them. One of the last pages says, "When friends come in/to play on rainy days/we show them all our shells./We tell their names,/just where we found them,/and all about the day/the waves ran up to meet us." These children must be the most boring people to hang out with! "You want to look at my shells again??" No, no I don't want to look at your dang shells! Don't they like, play? Like normal children? "Shells... shells... would you like to look at my shells?"
