Neightalie is often busy but goes out of her way to hang out with friends. When she isn't eating or drinking she loves dancing the night away. Nibbles enjoys seeing her friends have fun and will try her best to plan out the 'perfect night' which will often end in getting kicked out of a club but that isn't usually a problem with the plan and more with the adaptations of the plan as the night progresses.
Nibbles enjoys hijinks, usually convincing Violet to steal traffic cones or chug the entire fruit punch bowl. While Neightalie is the planner she is not the head of the group. Instead of thinking about Fair Flyer or Twilight, think of her more like the nerd side character whenever it comes to her planning, usually helps progress the plot but isn't the focus.
