Waddle Doo can be inhaled by Kirby in its Super Smash Bros. appearances, but does not provide the Beam ability due to the absence of traditional Copy Abilities in these games.
Can Kirby absorb powers?
Kirby is well known for his ability to inhale objects and creatures to gain their powers, as well as his ability to float by expanding his body. He uses these abilities to rescue various lands, including his homeworld of Planet Popstar, from evil forces and antagonists, such as Dark Matter or Nightmare.
