Seems Like the Legend Of Zelda 100 pit Trials.
The hardest floors in the dungeon are here, even the battle ahead isn't as
difficult as these battles. The Feeling Fine Badges really help here and maybe
using the Jumpman and Power Bounce Badges isn't a bad idea either. Strengthen a
certain attack and use it through out these floors, be sure to use Supernova
when ever possible since you'll be regaining Star Power really fast since the
enemies are difficult. If you run into an Amazy Dayzee be sure to kill it on the
first turn, do what ever it takes because they reap a large amount of Star
Points and should help to level up and recover.
