On International Women's Day there is a big rap duel and Max has signed up the Boombastic Ninjas to rap the T-Rex Crew into the ground. But unfortunately he hasn't read the conditions of participation, because at least one girl has to rap in every registered group. When Max learns from Barenboim that musicians are always on the lookout for new things to develop their music, even if it's a small triangle that plays a crucial role in the rhythm section as in George Bizet's "Carmen", he has a brilliant idea: Emilia should become a member of the Boombastic Ninjas and thus provide a breath of fresh air.
