The Chopper Form is the fourth transformation in Yooka-Laylee, located within Capital Cashino after players obtain the Mollycool by winning at the slot machine near Dr. Puzz and provide it to her to power the D.N.Ray machine. The Mollycool requires players to use Lizard Lash on the slot machine handle and Buddy Slam on the pressure plates to stop all three spinners displaying the Yooka and Laylee symbol simultaneously. Once transformed, Yooka and Laylee assume the appearance of a helicopter where Yooka’s body forms the cockpit while his tail creates the engine and rear section, and Laylee’s head resembles the propeller top with her wings forming the rotor blades. The helicopter features three black wheels with orange covers positioned on the bottom for landing, a red tail fin for stability, and a missile launcher mounted on the chin for combat applications. The transformation grants flight capabilities throughout Capital Cashino, enabling access to elevated areas, rooftops, and platforms that remain unreachable through normal jumping and climbing mechanics. Flight controls allow vertical and horizontal movement with unlimited duration, providing comprehensive aerial navigation throughout Capital Cashino. The combat system involves firing missiles at enemies, breakable walls and environmental obstacles that block progression through various areas. These missiles prove effective against laser turrets that guard restricted sections and can destroy cube-shaped rock formations blocking access to the Shooting Gallery and other specialized zones. Additionally, the missiles can eliminate non-functional slot machines positioned throughout Capital Cashio, revealing Casino Chips hidden within these broken gambling devices. Also, the transformation enables completion of escort missions involving Sir Scoffsalot and his fellow pig knights, who only communicate with Yooka and Laylee while in helicopter form. These characters provide cryptic riddles indicating their desired destinations, such as requesting transport to areas with trees or specific landmark locations within the casino. Successfully completing these timed escort missions within the time limits rewards players with Casino Chips, which function as the primary currency system in Capital Cashino where ten chips exchange for one Pagie through the Casino Banker. Furthermore, it provides essential access to upper levels of the casino structure, including areas above the gaming floor where additional Casino Chips, collectibles, and puzzle elements await discovery. The Chopper Form remains active until players manually return to Dr. Puzz’s D.N.Ray platform or collide with water.
