Maggi and Milo return in another adventure. This time Maggi and Milo are having a staring contest when Maggi’s mom suggests going to the park. Maggi wonders why they should go and mom replies, “Because it’s Tuesday and the sun is shining and you might make a new friend.” Maggi doesn’t think she needs new friends because she has “Milo, the Mammal of All Mammals.” They go to the park to discover that dogs are not allowed. Maggi’s mom says she will stay with Milo while Maggi goes to play. Maggi introduces herself to a group of children and soon they are playing. Maggi decides that she wants to walk Milo because he looks bored. The other children want to walk him too. Maggi says that it is expensive and sends them to look for roly-polies, sticks, acorns, dandelions and three leaf clovers. She decides that they look like they are having fun collecting things for her, so she decides to join them. Maggi leaves the park having made new friends, but with her best friend of all, Milo. This is a fun story about making new friends.

The illustrations are colorful and engaging. The characters in the book reflect a multicultural group of friends.
