This stage is the boss rush. There are platform stages between the bosses, but they are all very short with only one or two things to figure out for each stage. Each might be easier with a particular technique, and in the end it should be possible to get through to each boss with a lot less trouble than defeating the bosses themselves.
Boss 1[edit]
Gourmet Ogre is the first boss the Prinnies face here in the Sweet Palace. This fight shouldn't be much different from that in the Nethergrasslands, although he does have a new skill which shoots three fireballs, and tends to do two roars in a row. Choose a method that works for you and stick with it, or simply do whatever it takes to take health off of him. He's easier to hit with a Hip-bump from behind, and the Prinnies' slashes can hit him no matter what he does.
Boss 2[edit]
Anise is the second boss in this stage. If you faced her in the High Tome Forest, this will be a familiar battle. Follow her around and Hip-bump her when she leaves cat form. It should be possible to ignore most of the enemies she summons (or just take them down with the same air slashes being used against her). Again the biggest concern is the spell she sometimes casts when her health is critical, which will zap the Prinny with an energy beam.
However, if you faced Kim and Chi in the High Tome Forest, you will encounter them for this fight. They behave pretty much the same, but each have two additional stun counters, and start on the same side of the screen. Chi is the more annoying of the two due to her flaming sword attack, so try to bring her down first.
Boss 3[edit]
Basil & Chervil take the next spot in the Palace. This battle's the same as in Death's Watchtower. Basil will most likely be the first to go down simply because he travels across the stage on the ground, while Chervil burrows underground. Basil will launch skulls when he gets the chance, but they shouldn't be much of a concern, since they can be Hip-bumped away as you attempt to Hip-bump Basil.
Try to finish off Basil as close to the right-hand wall as possible. If his skull falls against the wall, the skulls he launches from his mouth for the remainder of the battle will disappear into the wall immediately. Chervil's movements underground will result in the ground rippling where she is about to break through. This is your best chance to stun her with some Hip-bumps, and from that point on its best to keep her stunned until the stage is complete.
