After completing the whole event map, you have a chance to spawn a bonus area after finishing any event map. The bonus area will appear over a random event map, like 1-1, 2-4, or 5-3. Their vitality cost will correspond to the event map it appear on. You will see a red pulse effect on the event map icon. I don't know if there is a timer on it or not, but if you finish the bonus area it will close and you have to spwan it again. It is possible to have multiple bonus area to appear one after the other, because completing the bonus area count as completing an event map. I suggest run through 1-1 repeatedly because it costs the least vitality.
