A trip to the Netherworld

Arnold was so curious about those mysterious things happening, like voices that are unfamiliar, unexpected visitors, and many more, that he wanted to investigate about Sabrina and her family.

He made a plan to see if they were doing something strange. The plan was visiting Sabrina together with Gerald, Phoebe, and Helga. After they enter, Arnold will be excused to the bathroom, then look at their personal things. There were potions, spell books that made him more curious. Helga was looking for Arnold then she saw him looking for something. She was upset. She said "GET OUT OF THERE, FOOTBALL HEAD!! WHY ARE YOU SNEAKING ON SOMEONE'S PRIVATE THINGS?". Arnold simply replied " You're right. Let's go back." They fixed the place then went back to the living room. Unfortunately, Hilda made a mistake on her spells that brought all of them to the Netherworld!!

Since the four of them were mortals, Zelda said "you four should stick with us witches!". "You're witches?!" asked Helga. "Y----es!" Sabrina said with fright. They looked for a portal to go back to their boarding house. They also knew that Salem talked.

This was weird, but they were actually in the Netherworld with not one, not two, but FOUR mortals!!!
