You don't have to get the bar into the green; the bar is a range of % chance of success. With each successive tower the chance is lower and the requirements to move the bar go higher. For Broodby level 1 its 6% to 20% and for Phaun level 1 it is 2% to 10%. The nominal required dragon levels are 35 and 40 Broodby and Phaun respectively. That is the level that will max out the bar assuming every dragon matches all the elements.
