#1 New York Times Bestselling author and illustrator Mo Willems is best known for his Caldecott Honor winning picture books Don’t Let the Pigeon Drive the Bus and Knuffle Bunny: a cautionary tale.

In addition to such picture books as Leonardo the Terrible Monster, Edwina the Dinosaur Who Didn’t Know She Was Extinct, and Time to Pee, Mo has created the Elephant and Piggie books, a series of early readers, and published You Can Never Find a Rickshaw When it Monsoons, an annotated cartoon journal sketched during a year-long voyage around the world in 1990-91.

Mo’s work books have been translated into a myriad of languages, spawned animated shorts and theatrical musical productions, and his illustrations, wire sculpture, and carved ceramics have been exhibited in galleries and museums across the nation.

Mo began his career as a writer and animator for television, garnering 6 Emmy awards for his writing on Sesame Street, creating Nickelodeon's The Off-Beats, Cartoon Network’s Sheep in the Big City and head-writing Codename: Kids Next Door.

As I have mentioned before, my daughter LOVES Elephant and Piggie. Right now this one is her current obsession and ranks an 11 on the "I Need to Find a Place to Hide This Book While She Is Asleep, Because If I Hear 'Let's Read It Again' One More Time, I May In Fact, Lose My Mind." It's the newest in a long line of such books, but I've remained a good dad and have not actually hidden any of them.

The plot is simple. Piggie pretends to be a frog and Gerald is more than slightly confused as he thought she was a pig. It's a story about pretending, and how to use your imagination.

Again, these books are consistently amusing for my daughter (and I would assume most young children). There's enough winks and nods to adults to keep them amused, as well as some genuinely amusing lines (my personal favorite is when Gerald asks if grown-up people pretend, to which Piggie looks at the reader and says "All the time.")

Overall, this is not in my opinion one of the better books in the series, but as it's the current obsession book, it's the one most on my mind. 3/5 stars. Fairly amusing, but there are better books in the series to check out.

Neo took us on a little adventure, alongside Gerald and Piggie, into the life of imagination. When Piggie declares that she is a frog, Gerald is both baffled and a little annoyed. No matter how loudly Piggie ‘ribbits’, Gerald will not accept that his friend is a frog. However, Piggie explains the art of using one’s imagination, which opens up new portals for both elephant and pig to explore worlds they could not have discovered otherwise. Neo continues the art of reading and does well with this series that is both exciting and easy to read. Hoping we will get through many more on our lead-up to a much needed holiday break.

My son is a Mo Willems fanatic. He has Autism Spectrum Disorder with speech delay but reads at a fourth or fifth grade level, pretty amazing since he's not yet five. Anyway, we've read this book together five or six million times. Sometimes he's Gerald the Elephant, sometimes he's Piggie. It's Mo Willems book so you know what you're getting, humor for kids and adults and Peanuts inspired art.

The reason I bring this up is because last night, my son PERFORMED the Piggie parts, hopping around on the floor like a frog, ribbiting at appropriate times. It was adorable.

Piggie teaches Gerald how to “pretend” just for fun and giggles.
Very cute story and the illustrations are once more exceptional. Simple but also extraordinary!
Note: Look for pigeon. He is somewhere in the book barking and pretending to be a dog.

This book is just so ultra-silly. I read it and couldn't stop smiling. (My grandson got a copy for Christmas.) He didn't read it with me, he just handed it to me and said 'read.'

I don't know how to describe the appeal of these books. Simple ideas. Fairly simply words, though sometimes a 'big word' sneaks in, when it's needed. My grandson was having some difficulty with his reading - he's in second grade - and math is more his thing. But with these books he's smiling and laughing and reading, then re-reading.

I love this author. I love his books.

Literal and practical Gerald isn't quite sure what to make of imaginative and impulsive Piggie's declaration that she is now a frog.

My 4-year-old and I are big fans of Mo Willems' Elephant and Piggie books. This one is a real favourite because it is delightful to read out loud, and the message is that pretending can be fun and that there is nothing wrong with being silly and playful.

This is a great book for reading out loud, and for kids who are just starting to read. It is also excellent for pre-schoolers who are just starting to get into pretend role-play.

This was such a fun book. I read it to Bug once and she can tell the story by herself now. She also spent the majority of the afternoon pretending to be a frog.

Hooray! Frog and Piggie are back. Piggie teaches Elephant about pretending. Piggie tells Elephant, "Everyone pretends." Elephant asks, "Even grown-up people?" Piggie's expression is perfect! "All the time."

I read this book out loud to my grandchildren today, and my reluctant reader begged me to read it three more times! A fun encouragement for children to use their imagination!

Loved it! Hilarious and had me actually laughing out loud at times. Great for kids and adults. There are even some lines that might be more appealing to adults.

I probably sound like a broken record on these reviews but these books are truly great. Nicely illustrated, fun and containing a nugget of a teaching. This one was really funny too.

Yay! Another Elephant and Piggie story! We read them as soon as we can get them at our local library. We just love these books and our girls love to play the different parts.

With only two main parts, I get to sit back and listen to our girls read the book to me. I love how Mo Willems includes lots of varying volumes and enthusiasm in his dialogue and I was so impressed how our girls used different inflections in their voice to convey these changes.

Younger children will love the repetition and even older children can appreciate the twist in the story. The illustrations are just as fun as we've come to expect from the books in this series and our girls love looking for a 'hidden pigeon' in the endpages.. I love the expressions on Gerald and Piggie - you can really see their emotions.

Overall, we really enjoyed reading this book together, and although our girls have outgrown the reading level of these books, we all really love them anyway.

Sophie (1st grade) read this on Jan. 7, 2021.

Piggie (a female pig) wants her friend Gerald (a male elephant) to accept her new "identity" as a frog (and eventually he does and pretends to be a cow), but they both acknowledge that it's just pretend. No matter how much a pig wants to be a frog or thinks that it's a frog, it's not—it's still a pig. Cf. I Don't Want To Be a Frog .

I use the "sexuality" tag because of the current debates about gender fluidity. Clear definitions and distinctions regarding essential qualities may be difficult to articulate sometimes, but that difficulty does not necessarily indicate that X = Y.

I've read this book multiple times in my ENG 1304 course at Baylor to talk about claims of definition. I also show this video.

Logan is just beginning to read on his own and these books are perfect for that. Willems is so good at writing for new readers while keeping it funny and engaging for kids and grown-ups alike. In this book, for example, he has Piggie introduce the word "pretending" to Gerald, and because its new, Piggie says it slowly, "pre-tend-ing." On the opposite page, Gerald says it again, "Pretending?" So, the reader first sees the word broken into manageable and less intimidating parts and then all together, all within the plot. Pretending is used several more times throughout the books. I can't recommend this series enough for new readers.

When Piggie comes hopping and ribbiting along, Gerald is understandably confused. After all, pigs don't behave that way. Piggie lets him know that she is just pretending to be a frog for a little while, and encourages Gerald to join her. Not surprisingly, Gerald is reluctant to do so since he doesn't want to hop and eat flies all day. Beginning readers will laugh as they listen to the argument and watch what happens when Gerald finally decides to moooove into a new personality. It's hard not to smile while reading about the antics of these two very different friends.

Gerald and Piggie show us once again how fun picture books can be. Piggie declares herself a frog. Gerald is trying to realize how she has managed to turn into a frog (and still look like a pig) and through it learns what pretend is and that anyone can do it (according to Piggie, adults do it all the time)
