To save two worlds, Kirby's final mouthful must be his biggest! It looks like a lot to handle, but he seems totally fine somehow. Go, Kirby! Carry your and Elfilin's combined hope for the future! Race through the sky and deliver the final blow!
— Figure description from Kirby and the Forgotten Land

Big-Rig Mouth is a Mouthful Mode and Last Battle Ability in Kirby and the Forgotten Land. It involves Kirby wrapping himself over the top of a semi-truck with a trailer in order to take control of it, allowing him to drive around at high speed and run over enemies. It functions much like Car Mouth, except that it is used exclusively during the final phase of the fight against Fecto Elfilis. Big-Rig-Mouth Kirby has difficulty turning while he is driving forward, but he can power through any obstacles in the way. Near the end of the fight, Elfilin uses his power to propel Big-Rig-Mouth Kirby through the air, and give him the strength he needs to break through Fecto Elfilis' last attempts to destroy him using falling debris.


  • A (or B) - Jump
  • B (or Y) - Turbo Dash: Kirby speeds up, allowing him to bust through obstacles and flatten enemies, but becomes more difficult to control.
