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.
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.
