The Big Chicken is a 'monster drop' and a consumable that was introduced during the Ratboy's Nightmare Update. It is one of the many collectibles that are needed by the players in order to complete the entries of the Itempedia of the Nightmare. Valid ways of acquiring the Big Chicken include the following:
- A possible drop from the Goons.
- A possible serving served from The Deli's waits.
- A possible reward from the Guttermouth Cells.
In appearance, the Big Chicken is composed of a big baked chicken at the very center of the red-and-white dish below it. Two chicken legs can be seen sticking out on the sides of the baked chicken.
The Big Chicken can be used and consumed by the players to restore 500 HP back to the players' health pools. In addition, the players will receive 5 extra stamina points, enabling the players to attack and/or escape from threats if their stamina bar is low.
This does not increase the maximum stamina pt. capacity from 10 to 15, but acts as an 'emergency backup' if the player is in danger. The Big Chicken can also be stacked on top of each other, making it an effective and beneficial consumable in places such as the Nightmare and the Otherworld Tower dungeon.
- The Big Chicken is one of the first consumables in Fantastic Frontier that uses the term 'Energy' instead of 'Stamina.'
