Kirby and the Forgotten Land is getting a lot of attention for its switch to 3D platforming, and for good reason. It's a very different angle of traversal and exploration from the usual Kirby fare. It isn't the only new feature that HAL Laboratory has in store for Kirby fans, though; not only does Kirby and the Forgotten Land have new Copy Abilities, but it has a Copy Ability upgrade system that lets fans customize each of Kirby's special powers, as revealed by the latest trailer for the game. That same trailer spotlighted another odd Kirby ability that seems themed around manipulating Kirby's environment: Mouthful Mode.
