Percy found himself in a small room with a bowl of candy, and a sign that says "take one." Percy took a piece of the monster candy, and put it in his pocket for later.
He went out, and started walking to the door on the opposite side of the room with the Froggit.
Before he got there, though, he ran into a different Froggit, and a Fight began. Percy decided he'd try to use Mercy, but felt like it wasn't time yet.
Percy complemented the Froggit instead, saying he was a good little frog. Froggit didn't seem to understand, but was flattered anyways. "Ribbit," said Froggit, blushing deeply.
The frog hopped straight at him, and Percy stepped to the side, not wanting to get hit head on by the big 'ol guy.
Next it was Percy's turn, and he felt like it was time to use some Mercy. He spared the Froggit, and the monster hopped away. It actually also left a few gold pieces on the ground for him.
Percy smiled, satisfied with how that went, and after pocketing the gold pieces, went forwards into the next room.
That area had a pitfall, and then he had to climb back up to the other side of the hole. Ow. It was not pleasant falling down deep pits, but he had fallen down more than his fair share, so it's not like it was anything new.
When he entered a room with a large rock in front of a button, his cell phone rang. "Hello? This is Toriel. For no reason on particular... Which do you prefer? Cinnamon or butterscotch?"
Percy thought about it, and responded, "butterscotch."
"Oh, I see." Toriel said. "Thank you very much!"
Toriel hung up, and Percy started walking on again, but after another step and a half, she called again, and asked him if he dislikes cinnamon, to which he responded with a no.
She hung up for real this time, and Percy went on. In that room he just had to push the rock that was there onto the button, and the spike wall retracted.
Before he had quite finished that, though, he encountered a monster he soon found out was a Whimsun.
The Whimsun approached meekly, and they entered a Fight. Percy started to try and console the monster, but halfway through his first word, Whimsun burst into tears and ran away.
Disappointed, Percy finished the puzzle, and walked on. Toriel actually called him again right here, and asked if he had any allergies. He said no, and she soon hung up.
In the next room, it was just a matter of falling again, until he figured out what he was supposed to be doing. As he was figuring it out, he ran into another Froggit, and Percy complemented and then spared it like he did the last one.
The room after that had a talking rock, and he had to ask it politely to move to the button there. The spike wall retracted, and he soon moved on.
The next room was empty except for a table with moldy cheese stuck on top, and a mouse hole in the wall. Percy walked on.
This room had a narrower area between the walls, and right there, lying on the ground, was a ghost.
Percy walked up to it, and the ghost kept saying "zzzzzzzzzzz," with an "(is he gone yet)" sprinkled in the middle.
Why this ghost was pretending to sleep, Percy didn't know, and why this ghost was actually stopping him from moving forward, he was REALLY confused about.
"Excuse me," Percy said, "would you mind moving to the side a bit so I can walk past?" The ghost responded with even more persistent "zzzzz" sounds.
Percy gently nudged the ghost to the side a bit, and he immediately entered a battle. Well, here comes Napstablook. Percy felt like that was the ghost's name.
Even though he had entered a Fight, Percy decided he'd try to solve this mess again without violence. He gave Napstablook a patient smile.
"heh..." The ghost said, then started to cry acid tears.
The tears caught him by surprise, but they actually only hurt him a little bit, so it wasn't too bad.
When he got hit by one of Napstablook's tears, Percy saw a bar with numbers flash in front of him. It said, "HP 249/252." To the left of it, something else said, "Percy Jackson - LV 59."
