Brumm

Brumm is one of the members of The Grimm Troupe. He plays an accordion just inside of Grimm's tent. When the time comes, he can help the Knight drive The Grimm Troupe out of Hallownest if they so choose.

Trivia

 * Despite wanting to end the Ritual once and for all, Brumm still is loyal to the Troupe and he finds it difficult to oppose the Master. He started to question why the Troupe performs the Ritual and the impact that the Ritual has on fallen kingdoms. This possibly led him to conclude that he and the Troupe are slaves to the Ritual and are bound to perform it anywhere they are summoned.
 * When examined closely, it can be seen that the instrument he plays on has limbs, implying that it is a dead or live bug.
