This level is only available when there is a Daredevil Comet in orbit in Ghostly Galaxy. Whilst the comet will appear at random, you will need to complete Beware the Bouldergeist first.
Bouldergeist Boss Fight
This fight is essentially exactly the same as the boss fight in Beware of the Bouldergeist. The big difference is you cannot take damage in the comet version. Therefore, you’ll need to be extremely careful with your moves and tactics to avoid getting hit. This can be tricky but if you follow the guide for the regular boss fight you should be able to complete this one without taking damage.
