The Aliens are characters that appeared in the Kirby: Right Back at Ya! episode Junk Jam. While just a trio of intergalactic garbage men, these three mistook Dream Land for a dump and started pouring their trash everywhere from within their spaceship. Not long after Fire Kirby destroyed Fire Lion, the aliens were nice enough to clean everything up once they realized their mistake -- and then went and disposed of the trash by dropping it into the atmosphere, where they burn up and became shooting stars.
Other than their differences in width and size from each other, the aliens share the same physical appearance. They have dark pink skin with even darker pinkish gray hands. They wear green overalls and have neon green eyes and alien-ish mouths on top of their heads. It can also be noted that the aliens are very Cappy-like in appearance.
