Since UFOs create wrappeds, 3*42=126.

500-126=374 wrappeds more to create.

Candy bombs+Chocolate spawner+3 colours+mystery candies (either good or bad outcomes, as what you said, commonly produces wrapped candies) will be a very fun level and I'd rate it as... Somewhat easy. You can't tell when you'll have a lucky board or not. 500 wrapped candies is considered a risky order.
