It runs through a text of a standard day visiting grandpa - but something is a little odd.
The text never describes any aspect of the house, but oh boy, the illustrations sure do. Is it the tiger being fed in a highchair? The dog playing a card game with them (all the cards are the 8 of hearts, and grandpa cheats, which is probably how he always wins)? The cowboys in the living room?
Every page is full, simply full of tiny details and big details that are strange, unusual, or just a little weird. Every time I open this book, the nieces (5 and 2.5) fall all over themselves to find something new to point out as silly. We haven't found everything yet, and we've had this book a few weeks now!
Naturally, of course, the thing that's "wrong" to our protagonist is something mindnumbingly banal - her grandfather put on the wrong socks this morning! Silly grandpa!
