This technique summons a Gourd Toad (瓢箪蝦蟇, Hyōtan Gama), a small, gourd-shaped toad, from Myobokuzan. The victim is then dragged into the toad's stomach, which is isolated from the outside world by a barrier. Inside the toad's stomach is a lake of strong acid that will dissolve anything that falls into it.
