In the fourteenth book in the Henry and Mudge series, it is Henry's birthday! There will be bright balloons, presents, and cake! For these two friends, it is more than a birthday, it's the best day of all!
At first Henry's very neat cousin doesn't like the cookies from under his bed or Mudge's slobbery kisses, but when they all play frisbee, she begins to enjoy her visit.
For Henry and his big dog Mudge, spring means admiring the first snow glory, playing in puddles in the rain, and watching the five new kittens next door.
No one loves to play more than Henry's puppy, Mudge. And when Fluffy the cat joins Mudge for a play date, the games are just beginning. From running to hiding to climbing galore, these two just might prove that cats and dogs really can be friends.
While trying out the spy glasses, spy hat, and other items in their new spy kit, seven-year-old Henry and his dog Mudge make a new friend and form a spy club.
