Jumpluff spreads cotton spores as it floats to create offspring, and once it runs out of spores its journey, and its life, comes to an end. Bulbapedia notes that at 6.6 pounds, Jumpluff is the lightest Pokémon that has undergone two evolutions, and its design and movements in games like Pokémon Stadium 2 evoke a cheerleader waving pom-poms.
In Hatch Me If You Can, multiple Jumpluff attacked Team Rocket during their attempt to steal Ash's Larvitar, motivating the Larvitar to use Screech and Hidden Power to send them blasting off. Gym Leader Ramos used a Jumpluff against Ash in The Green, Green Grass Types of Home!, where it battled Fletchinder and was soon defeated.
Jumpluff debuted in Neo Genesis as a Rare illustrated by Atsuko Nishida, and Aquapolis later added both a Rare and Holo Rare printing by Yuka Morii. It has remained mostly a Rare card since, including a Paldean Fates Shiny Rare illustrated by Lee HyunJung.
