A brainstorm is a way to produce ideas.
History[]
When Anxiety decided they needed ideas to change Coach Roberts' mind about Riley not being ready to join the team, she started a brainstorm. Soon, ideas started to fall into Headquarters, but Anxiety declared that they were not big enough and so called for bigger ideas. Eventually, a very large idea came into Headquarters which Anxiety used to make Riley dye her hair to fit in with the Firehawks.
