Leafan is a stumpy, brownish-red blob with beady eyes and large green leaves fanning out from the center of its body.
Leafan floats down from the sky like Bumber from Kirby 64: The Crystal Shards and, upon landing, will start to launch seeds out of its head. Sometimes, Leafans can be found already sitting on the ground. If Kirby touches a seed, he'll take damage.
Leafan leaps into the air and floats back down after each seed attack. Bulby, another Leaf-yielding enemy in Kirby's Return to Dream Land, does not appear in these games, making Leafan the only source of the Leaf ability (aside from Copy Essences).
Leafan's name is a portmanteau of leaf, referencing the enemy's greenery, and fan, referencing the fan blade-like shape of its leaves when drifting through the air.
