Enter Groat's kitchen. Battle through creep cakes, current cakes, and constructs to find out what's wrong with Groat.
On the right side of the map is a freezer-like area featuring freeze grate and slush block hazards. Find a button hidden in the area and retrieve the key. On the left side of the map is an oven-like area featuring fire that must be removed with water orbs. Retrieve the key to continue to the boss fight. Ignore respawning monsters.
A giant "mixing bowl" is the location of the miniboss fight. It is a relatively harmless vortex that moves players and monsters around the central mixers between waves.
: The fire and freeze grates seem to be reminiscent of the hazards of a real world industrial sized kitchen. In addition to these, there are several militaristic hazards strewn about, similar to those used in Gremlin warfare.
