Wigglytuff's body is very flexible. By inhaling deeply, this Pokémon can inflate itself seemingly without end. Once inflated, Wigglytuff bounces along lightly like a balloon.
Zubat avoids sunlight because exposure causes it to become unhealthy. During the daytime, it stays in caves or under the eaves of old houses, sleeping while hanging upside down.
Oddish searches for fertile, nutrient-rich soil, then plants itself. During the daytime, while it is planted, this Pokémon's feet are thought to change shape and become similar to the roots of trees.
Gloom trickles sticky nectar from its mouth with the appearance and consistency of drool. This can be used as a fertilizer for plants. Both this nectar and the flower on Gloom's head release a foul odor strong enough to induce fainting in humans over a mile (1.6 kilometers) away.
Vileplume can shake, flap, or burst its petals into bloom with a bang in order to release clouds of pollen. This pollen is yellow and highly allergenic to humans, and toxic to other Pokémon; Vileplume uses it to paralyze its prey before devouring it.
Paras has parasitic mushrooms growing on its back called tochukaso. They grow large by drawing nutrients from this Bug Pokémon host. They are highly valued as a medicine for extending life.
