As Juliet and Nick get tricked into the bus that Mariska (disguised as Rosalind) is controlling, Mariska lures them into her mind. When Juliet reaches the area, they are presented with a psychedelic area. Juliet lands on a platform that is a combination of school buses clumped into one circular form, with eight American flags on the side. In the middle of the platform lies what appears to be a portal, as Juliet and Mariska manage to enter the area through there. The rest of the stage is surrounded by a dark, kaleidoscope-patterned background.
The phase starts right after Mariska (disguised as Rosalind), lures Juliet into the fight. She then reveals herself to them and welcomes them to her "world" and the battle begins. Mariska uses long-ranged attacks such as shooting bubbles that try to entrap Juliet and decrease Juliet's health. Once Juliet defeats her, she slices her in half.
This phase begins when Mariska reveals that she can multiply herself by tearing in half at the seams. Not only is she able to bubble blast in this phase, but also complicate her with attacks with tractors and Chicken heads attached to elongated, mechanical necks. When defeated by Juliet, she is sliced in half a second time.
Mariska will then tear herself once again to multiply, but in this phase there are eight of her. She then conjures attacks that emulate certain events or deep thoughts of Mariska. These attacks include an enlarged version of her hand, rainbow-colored butterflies, firework bombs and a rocket ship. When she is defeated, Juliet will cut her by aiming for her collar bone, beheading and defeating her.
