Og heads to summer camp in the third book in the middle grade companion series to Humphrey!

Og didn’t know where he would end up when school was over, but it turns out Camp Happy Hollow is just about the best place ever. Lovely nature is all around, friends from Room 26 are there–including Humphrey!–and camp days are full of exciting activities.

Og has lots of new responsibilities, like watching out for Humphrey, helping his fellow campers adjust to being away from home, and encouraging everyone to always try their best. But when one camper lets Og loose at the lake, he is in a tough spot. The lake sure does feel like home, but so does his tank. Plus his human friends need him–and so does Humphrey. Good thing Og has experience in the wild because–BING-BANG-BOING!–this is going to be one hopping summer!

Og’s frog’s-eye view of summer camp is silly, caring, and adventurous–the perfect companion to Summer According to Humphrey.

EXPLORING ACCORDING TO OG THE FROG
Book 2 – July 2019, Putnam/Penguin, 160 pp
Og the Frog would love to explore like his pal Humphrey, but he can’t climb like a hamster, and he worries he’ll dry out if he leaves his tank for too long. But Og knows that taking risks can pay off and he’s determined to help his classmates understand this, too. Whether it’s finding the courage to share an out-of-the-box idea, helping a sister begin to listen to her little brother or inspiring a special needs child to show his hidden talent, Og encourages everyone to be brave and go after their dreams. And if he fully embraces his frogginess, maybe he can explore as much as Humphrey!

LIFE ACCORDING TO OG THE FROG
Book 1 – July 2018, Putnam/Penguin, 160 pp
The adventures in Humphrey’s Room 26 are hopping back into the spotlight, from the perspective of Og the Frog! When Og the Frog first comes to Room 26, he doesn’t know what to think. He misses his friends from the pond, there are all kinds of strange noises, and the water is his tank just might be too clean (you know, a little muck never hurt anyone). But the furry, squeaky fellow living next to him is endlessly entertaining, the kids sure are friendly, and–BING, BANG, BOING!— he gets lots of inspiration for making up poems and songs. But he gets stumped when talk turns to sending him back to the pond. Will he have to say goodbye just when he’s starting to feel at home?

Og’s frog’s-eye view of the world is curious, sympathetic, and poetic, and the perfect companion to The World According to Humphrey.
