freebirdmom Also try to remember you get an Energy Bonus every time you jump to the next level. So do Vortex Island Challenge first and complete it. Clearing it will take 24,713 in Energy, which you will get back as Experience Points. There are 22,500 Experience Points to be had from the Experience Boxes in that Challenge, and a 28,000 Experience Points Clear Bonus to clear that Challenge. That's a total of 75,213 Experience Points you will accumulate from doing and clearing that one Challenge, which will take you to your next level and give you a bonus of over 2000 in Energy to help you further.
If you were able to finish the Superheroes Event, then after clearing Vortex Island Challenge you might want to try clearing Pursula's Secret Laboratory Challenge, because doing so should be attainable before the Event ends. You could instead cherry-pick your way through the other Challenge Areas, but if you decide to tackle clearing Pursula's Secret Laboratory Challenge, then you will get back as Experience Points the 61,240 in Energy it will cost you to clear it. There is also a Clear Bonus of 62,00 Experience Points and 27,000 Experience Points to be had from the Experience Boxes in it. That's a total of 150,240 Experience Points you will accumulate from doing that Challenge, which will jump you nearly 3 more levels. A 3 level jump would get you a total of about 7000 in Energy from the Bonuses. So if you did both of those Challenge Areas and cleared them, then you would jump 4 levels and get around 9000 in Energy as a Bonus. Something to consider.
Those two Challenge Areas will also give you 50 Starfish. If you haven't spent any of your other Starfish yet, then you would have a total of 281 and that is more than enough to get the Pursula's Crown.
