Froggy isn't looking forward to his check-up because he might get a shot but when it's over and he's pronounced a very healthy frog, Dr. Mugwort is the one who dreads Froggy's next visit.
Froggy hoped for a brother to play with so he is disappointed with his new baby sister, Pollywogilina, but only until she is old enough to start learning from her big brother.
On a class trip to the pumpkin patch, Froggy exuberantly picks a pumpkin in hopes of carving a jack-o'-lantern, making a pumpkin pie, and possibly winning a prize in his class's pumpkin-picking contest.

Froggy is very excited about his first Winter Carnival, and even though Mr. Mugwort has the day carefully planned the time for building a special snowman finally arrives.
