(This is before the music box was destroyed)

Mabel was walking around just...being Mabel. "La la la la, walking around in circles." She sang while walking in circles as said. She then saw a box. "Hey dipper." She asked her brother. "Hmm?" Dipper asked.

Mabel asked "Did uncle ford or Stan get this from an alternate universe or a yard sale or something?"
Dipper said "Not that I know of. And I don't read anything like that in the journal before they were destroyed. So I have no idea what that is.

It looks like a normal music box to me. I don't get what's so special about it. Well I'll see you later, me and Wendy are going to another funny security video voiceover, it'll probably be all day." Then he left the room.

Mabel then did every test to see how it was special to be in the mystery shack. She tried touching it, sniffing it, hearing it as she shook it, she knows not to taste it after some incidents a few days ago.

*cutaway time*
Mabel was using her tongue to taste weird things, like gum on the side walk, lampposts, stamps, leaves, anything's that wasn't food, she licked it.
*cutaway time over*

She then did the one thing that nobody should've done ever since Pandora's box, and that's not to open it. She saw a glow and she screamed as she was then taken to a new world away from her original home.

Soos who happened to be in the other room looked around completely confused on what he heard. Then he placed the box back on its original pedestal.

Mabel continued screaming as she was in another world, giant bugs, giant birds, and anamorphic frogs, were around the place. She walked around in awe, as the frogs were shocked to see a human in they're home.

Then she saw a frog that was weird, just like her. She walked over and said "Hi I'm Mabel what's your name?" The frog saw Mabel's cheerier nature and blushed "M-maddie." "Well Maddie, want to tell me where I am as we walk?" Mabel held a hand out. "Sure" Maddie replied as she took Mabel's hand. They walked and talked as they continued to hold hands.
