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: the battle starts when he throw his beakers to hit the player and then he throw 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 out the platform and him falls. 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, Brio scattering N. Verted Gems and Bumpa Berries.

Trivia

 * This N. Brio boss fight, him throwing his beakers to free his jellies and then drinking his potions to transform into a monster are a reference from the first N. Brio boss battle in the first game.
