When Huey, Dewey, and Louie come down with a bad case of the Duckburg McMeasles, Donald calls Grandma Duck to come watch them. Grandma must keep them entertained all day so they will stay in bed all day, and thus comes up with many activities and stories for them.
- A disease known as the Duckburg McMeasles exists, the symptoms of which include "watery eyes, sniffly noses, ruffled feathers, chills and some reddish spots on the beak.
- 10-15 years ago, a man named Mr Jumble's fruit cart tipped over, an event which Grandma Duck seems to remember fondly.
- As a young girl, Grandma Duck enjoyed making soap boats.
- Huey enjoys animal cracker soup, Dewey enjoys hot lemonade, Louie enjoys hot cider, and Grandma Duck enjoys grapple juice cooler.
- There exists a person known as Cartwheel the Clown.
- For Scrooge McDuck's birthday in 1984, Grandma Duck knitted him a money bag.
- It is mentioned that Donald Duck's and Scrooge McDuck's birthdays occur at close to the same time. This is consistent with their usual canonical birthdays of June 21st and July 6th.
- An event once occurred at which either Donald took Huey, Dewey, and Louie to an amusement park where they rode in a horse-drawn wagon, Scrooge took them to a zoo and they rode in a horse-drawn wagon, or Scrooge took them to a zoo and they rode in an old-fashioned fire truck. Huey, Dewey, and Louie, however, do not recall the exact details, and all of these events may have in fact occurred, or some combination of them.
Behind the scenes Edit
Kerchoo! Get Well Fun was published as part of the Disney Things to Do series in 1984 by World Book Encyclopedia, Inc (a division of the Scott Fetzer Company). The story also serves as an activity book, as each of the things Grandma Duck thinks of for Huey, Dewey, and Louie to do is accompanied by step-by-step instructions on how to do it in real life.
The author and illustrator of the book are unknown.
While a story in its own right, the story also serves as a framing device for Doc Swaller and the Green-Spot Cure, in that Grandma Duck tells the story to Huey, Dewey, and Louie as one of the many things she thinks of for them to do.
