Trophy description
"A Stomach Pokémon. While it's a carefree Pokémon with a loveable face, it can swallow something the size of itself in one gulp. Its stomach is filled with gastric juices strong enough to dissolve whatever it eats. As it matures, it can learn Wring Out, which is as strong as the remaining strength of the opponent Pokémon. It evolves into Swalot."
