This is probably my favorite baby-age book of all time. Like the other Boynton books, it is easy to handle (the board pages are quite tough), very brightly illustrated with the most delightful drawings (imagine a hippopotamus hiding behind a tree!), and features a simple but wonderful story.
It seems that all the animals have wonderful things to do, and they scamper off to do them on every page...But Not the Hippopotamus!!! (a phrase repeated at the end of each page, to young children's delight). But then, something wonderful happens. The happy hippo is invited to join the others! And off he runs, full of joy.
But Not the Armadillo! And the very last page, the most nonsensical nonsequitor of all, is a lonely looking armadillo standing all alone. And hence the "amhoho." When my daughter was just over a year old, she began to talk about the "amhoho." When given her first push-toy, a brightly colored bumble bee, she squealed, "It's the amhoho!"
I don't know how long it took us to figure out that the "amhoho" was the armadillo on the last page of this book. My suggestion is: put a little amhoho into your lives with this fabulous book, the best of everything Boynton has done.
