Nine-year-old resident wimp Doldrum Whimper has a dream: to bulk up and become the buffest colt his town has ever seen, so he'll get some respect in school and no one will pick on him ever again. Except he's not actually bulking up from his current program.

But not to worry, the Rainbow Falls Traders Exchange has items for everyone's interests, and that includes the old strong stallion books that were all the rage back in the day. Why, there's tonnes of books about making winners out of wimps.

Only... one problem: he's only got enough for one trade, so he has to pick the right one.

This is going to be tricky.

Author's note: set in the same universe as Passiflora's Plight and Junior Flight Camp, taking place in between the events of those two. Reading either is not required for the purposes of this story, it just clarifies a few details.
