Molly Mischief and the big pet by Adam Hargreaves

Pavilion, 2017. ISBN 9781843653424
Molly, aka Molly Mischief or MOLLY!!!, has lots of ideas, some of which are not as good as others. When her dad takes her and her brother to the zoo, she decides that she would really like a BIG pet, one much bigger than Polka her pet mouse. And so she tries a few - a hippopotamus, a polar bear, a giraffe, a tiger, a rhinoceros, even a walrus - but none of them is just right. Even the ostrich and the snake weren't suitable - her family is so hard to please. But then she discovers the elephant...
When his father Roger died after a series of strokes in 1988, Adam took over the successful Mr Men series and even though it took him "years of trial and error" to perfect his father's art style, he persevered and it is that same canvas that adds the charm to this new series that will resonate with many children who have good but out-there ideas, annoying brothers, and a twinkle in their eye.
When almost-independent Miss 6 spotted this on the review pile, she pounced on it and did not surface until it was complete, and even after reading it she had so much to tell us as she speculated on the sort of pet she could/would have! A better recommendation than any fancy words I might write!
