Trouble Brewing

Trouble Brewing is the boss fight and the final story level of Tranquility Falls and the thirteenth main level of Crash Bandicoot 4: It's About Time.

Overview
Crash and Coco confront Doctor Nitrus Brio, as the battle starts when he throws his beakers to hit the player and then he throws his beakers to free his jellies. Just like in the first Crash Bandicoot game, the player must jump on or slide into those jellies to hit N. Brio until he transforms into a hulking monstrosity and the player must use Akano to spin him to the edge of the platform. After that, N. Brio is defeated, accidentally transforming into a pterodactyl and choosing to launch one last assault. Unfortunately, he lays an egg and flies off mortified; Coco is also shocked by this, but Crash claims the egg before getting dragged out by his sister. After winning this boss fight, the player unlocks the N. Verted Mode, with Brio scattering N. Verted Gems and Bumpa Berries across dimensions.

Trivia

 * The overall battle against N. Brio in this level is a reference to the N. Brio boss battle in the first Crash Bandicoot game.
