My wife and my mother in law remember a children’s book that they read together in the late 80s or early 90s, long since lost–and they have been searching for it for years to hopefully share with grandkids.
The book has illustrations only, no words, and has a similar illustration style to a “Frog and Toad” book.
The book features a little boy with a pet frog. The boy takes the pet frog out on a boat, and while out on the water to somehow another little frog joins the ride.
The first pet frog is secretly jealous of the newcomer and when the boy is not looking, the first frog kicks the other one off into the water, but then plays innocent.
These covert aggressions continue, and are apparently very funny. But the boy eventually figures it out and scolds the naughty frog.
I look forward to any help that you can give!
