Swalot

“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.”

— Pokémon Ruby

“SWALOT has no teeth, so what it eats, it swallows whole, no matter what. Its cavernous mouth yawns widely. An automobile tire could easily fit inside this POKéMON’s mouth.”

— Pokémon Sapphire

“Its powerful stomach acid is capable of digesting almost anything. The one thing in the whole world a SWALOT can’t digest is its own stomach.”

— Pokémon Emerald
