A diner breakfast, French cuisine and rum cake inspire the challenges the competing chefs face.

One chef's knife is replaced with a shark jaw. Other challenges include cooking out of-and on top of-a suitcase; and making banana-nut muffins.

A grilling competition. Included: one chef makes a dish that almost tastes like chicken; someone is given the disadvantage of being tied to a rotisserie; and an unusual burger battle determines the winner.

A twisted pan and a big burrito give the competing chefs trouble, as does a kitchen up a tree.

Host Alton Brown revisits some of the worst sabotages of all time. Included: cooking upstream; and canned chicken Parmesan. Also: making crepes becomes even more tricky.

Challenges are encountered while making artichoke dip, Stromboli and waffles.

The chefs tackle smoothies and oatmeal cookies; and one act of sabotage involves a ride on an elephant. Chef Susan Feniger appears as the guest judge.

Challenges are inspired by the circus. Included: corn dogs are prepared in a clown car; a ring of fire drives somebody nuts; and a chef goes three-wheeling, while making funnel cake.

An egg soccer match gets intense; two chefs literally can't get off each other's backs; and a bad memory hounds a chef, while making blondies.

A biscuit breakfast challenge must be completed by the chefs, while on bouncy horses; a stroller is an obstacle for two of the competitors to overcome, while making chicken nuggets; and the final battle involves long tools and short legs.

Haggis proves to be a hassle; Alton turns chopsticks into an obstacle; and key lime pie is not a sweet surprise for one chef in the competition.

Sabotages involve a bobsled, Swedish meatballs, peanut butter and jelly. Cat Cora is the guest judge.

Chefs, who operate food trucks, compete in challenges that test their skills at making breakfast sandwiches and burritos.
