Gulpin (Pokémon)

Multiple Gulpin debuted in Gulpin it Down, where they were eating all of the food in the harbor city Ash and his friends were in. Because of this, Professor Jacuzzi made several efforts to stop them, but one such effort wound up enlarging one of the Gulpin, as well as Ash's Treecko. Both were eventually restored.

In Defending the Homeland! and Beyond the Rainbow!, multiple Gulpin were living in the wetlands that Ash's Goodra was from. In Master Class is in Session! and Performing a Pathway to the Future!, they watched Serena's performance along with the rest of the wetland Pokémon. In A Diamond in the Rough!, they were seen when Ash and his friends returned to the wetlands.

In Volcanion and the Mechanical Marvel, a Gulpin was living at the Nebel Plateau. It was particularly close to the Volcanion guarding Nebel Plateau. Sometime ago, it had been abandoned by a Trainer whose last act before departure was to hug it. As a result, Gulpin came to associate hugging with abandonment, which nearly strained its newly-formed relationship with Ash when he also hugged it. Later, it helped Clemont to break the bonds holding Ash and Volcanion together by using Gastro Acid.

In A Rollicking Roll…, Team Rocket's Pelipper accidentally sent out multiple Gulpin from the Rocket Prize Master. They caused Goh, Ash, and a variety of Pokémon to get stuck together in a large ball, causing trouble across Vermilion City.

Gulpin in Super Smash Bros. Brawl

After being released from its Poké Ball, Gulpin will wait until an opponent passes by, then will use Swallow to trap and constantly damage them. The opponent may also be beat on while in Gulpin's mouth for extra damage.

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

• Pokémon Pinball: Ruby & Sapphire: Hitting the Linoone on the left of the Ruby Field will make a Gulpin jump onto the table. Making three appear will activate Travel Mode.
• Pokémon Mystery Dungeon: Gulpin runs the Link Shop in Pokémon Square.

Gulpin is available in Brilliant Diamond and Shining Pearl.

Gulpin, given its category, may be based on a stomach, given its round amorphous shape and the digestive gases it produces.

Gulpin may also be based on a single, giant poison gland or even a gallbladder, the green sac-like organ that stores gastric acid. It also shares similarities with some snake species known to swallow their prey whole, though its general shape resembles a slug, or also a sculpin, particularly the blobfish subspecies, known for their soft, blobby-textured carcasses upon washing up dead on shorelines.

Gulpin could be a shortening of gulping (swallowing). It may also be a combination of gulp and sculpin, as its appearance vaguely resembles the sculpin subspecies, the blobfish. It could be also a combination of gulp and in.

Gokulin may be a combination of ゴクリ gokuri (the sound of gulping) and toxin.
