SwalotvsGrafaiai

"When SWALOT spots prey, it spurts out a hideously toxic fluid from its pores and sprays the target. Once the prey has weakened, this POKéMON gulps it down whole with its cavernous mouth."

"The color of the poisonous saliva depends on what the Pokémon eats. Grafaiai covers its fingers in its saliva and draws patterns on trees in forests."
