It's pretty messed up that all this is running at the same time tbh. I assume the Katy stuff is going to be around forever like the red sprite event has been, so I can backburner that, but doing bonus stages while wanting to maximize MK grind to get the event points is a bummerToo much stuff to do, too little NRG.
King Mog + Story Event bonus stages + Katy Perry with the daily chamber of treasure *-*
