Kratos and Pinkie began their exploration of the Underworld, carefully searching for any sign of Helios or Calliope. Pinkie continued to keep her eye on Kratos, concerned he might be ensorcelled by whatever had conjured Calliope's song from his memory. Their first obstacle was traversing a large cavern via clinging to the ceiling. Pinkie, in the hopes of distracting Kratos from becoming too focused, walked across the ceiling upside down as though it were the floor, though she nearly fell when he didn't even notice. In frustration, when they began scaling cliffs afterwards and monsters clawed their way out to attack, she was rather brutal with them. None came after the first set, for some reason...although the cliff face did tremble in a few places for some reason.

At the top of the cliffs, a Medusa also attacked, though Pinkie tossed her over the side of the cliff in frustration. One look at her face sent the other two to follow the first willingly. The two adventurers then proceeded to climb their way up even more cliffs. At the top, they came across a pair of cyclopes, and they each took on one. Pinkie decided to vent some frustrated energy on hers, and leapt onto its shoulder.

"Hey! I'm over here!" she yelled in its ear. She then dodged out of the way just before its fist slammed into its head.

"Stop hitting yourself!" she yelled from by its other ear, followed by dodging the next blow to its own head.

"Stop hitting yourself!" she yelled again from her place on its stomach, dodging another blow.

"Stop hitting yourself!" she yelled again, hanging from its loincloth, then leaping free of the last blow.

She gave it time to recover from that before hopping to the back of the other cyclops's head. "Stop hitting yourself!" she yelled one last time, then leapt away.

Her cyclops had already thrown the punch, striking its companion on the back of the head, triggering a brawl between them that quickly terminated both of them.

When the third cyclops arose, Pinkie let Kratos finish it off while she took care of the monsters trying to attack him from behind. With the path once more clear, they continued on towards more cliffs, leaping from platform to platform.

After a time of clambering around and coming to a steep drop, Kratos paused, glancing towards Pinkie. "What?" she asked.

He shrugged his shoulders. "I was merely surprised you had not complained about the constantly going up and down as you had in the Temple," he mentioned.

He was caught off guard by Pinkie suddenly hugging him around the neck. "You aren't hyper focused!" she said happily. "That's wonderful!" She then bounced back to the ground. "I was beginning to get worried you'd gone magic puppet from the song." She turned back to the drop. "And even if it didn't make sense for an outside, natural area to have varied terrain with an inefficient path, this is the Underworld, Daddy. It's supposed to be frustrating!" With a giggle, she leaped downwards. "Geronimo!"

Rolling his eyes, Kratos followed.

Eventually, Kratos and Pinkie reached a large bell near a river. Pinkie, curious to see what would happen, ducked under the bell, clung to the bell pull, and proceeded to rapidly ring it by bouncing her head around the inside until Kratos pulled her out. Pinkie giggled. "That was fun!"

Kratos rolled his eyes. Before long, Charon's Ferry arrived. Kratos and Pinkie boarded.

"Who calls for the Ferryman?" Charon asked, his voice grating.

"Hi!" Pinkie said happily. "I'm Pinkie Pie! This is my Daddy, Kratos. Who are you?"

Charon blinked. This was not how mortals - living or dead - usually reacted to their first sight of him. "I am Charon, the ferryman. It is my duty to ferry the dead across the River Styx."

"What's wrong with your voice?" Pinkie asked. "Would you like some water to gargle? Alka seltzer? Maybe a lozenge?"

Charon blinked again, both surprised and...touched. This was the first time since he had been given this post that anyone - God or mortal - had expressed concern for him...and he didn't know how to handle it.

Pinkie then spoke up again. "By the way, we're looking for Helios. Atlas has him down here somewhere. Can you take us across the river to keep looking?"

Charon stared at her for a time. "I'm not supposed to take mortals across while they still live..."

Pinkie immediately folded her ears against her skull, lowered her head, and looked up at him with dewy eyes and a pouty lip.

Not even a god could have resisted that for long. "...but I suppose I can make an exception, just this once, since you are on a mission from the Gods." Pinkie's happy smile in response to this filled Charon's heart with joy, and for a single moment lifted the gloom of the torment of his existence and occupation. "You'll still need to pay the toll, for accounting purposes."

"Here ya go!" Pinkie said happily, handing him a cupcake.

He blinked at it. "I'm...really only supposed to accept coins..."

"Trust me," Kratos grunted, "it is beyond price."

Curious, Charon took a bite.

For the first time in hundreds of years, the denizens of the Underworld were caught off guard by the passage of the Ferry...and Charon singing a sea shanty, accompanied by a perky pink party pony.

"Yar har, fiddle-dee-dee!
Being a pirate is alright with me!
Do what you want cause a Pirate is free!
