Why Do Inflation Rates Suddenly Skyrocket?

Inflation is like when your favorite candy suddenly gets more expensive. Sometimes, it happens all at once, this is called sudden inflation. Imagine everyone in the town wants to buy a new toy, but there are only a few toys left. The shopkeeper knows people want it badly, so they raise the price of every toy. That's like how prices go up suddenly when too many people need something at the same time.
