I'll start out with a theme/idea. Someone will start with a sentence for the story, After that another person will add on with another sentence or two. Afterwards you keep going until you have at least 10 sentences in the story. Then someone creates another theme for example.
Theme: Cloudy days
Nub 1: It was a sad day....
Nub 2: Then a nub showed up.
Nub 3: That nub looked down at the sad people. The nub then cast a magical spell.
Nub 4: The nub's spell failed and the rain poured harder.
Nub 5: After five hours the rain finally stopped.
Nub 6: The nubs were soaked and yelled at the nub who casted the spell.
Nub 3: The nubs looked back at the sky.
Nub 7: They realized something beautiful.
Nub 4: The rain had made the plants grow!
Nub 5: In addition a mixture of colors were were in the air.
Nub 1: The nubs cheered and named it a rainbow! Which was named after the rain and the nub's name(Bow) who brought it!
Nub 2: The end!
You can go out of order if you want to! Have fun!!
