Slowpoke is a pink Pokémon that resembles a cross between a salamander and a hippopotamus. It has vacant eyes that never seem focused, curled ears, and a rounded, tan muzzle. It has four legs, each of which ends in a single white claw. Its long, tapering tail has a white tip. This tail drips a sweet, sappy substance that is attractive to many species of fish. Slowpoke uses the tail as a fishing lure. The tail often breaks off, but it will grow back. In Alola, its tail is often dried and used in home-cooked stews.
Slowpoke has a notoriously dim intellect and often forgets what it was doing. It takes a long time to respond to outside stimuli. For example, it can take up to five seconds to process pain and can take an entire day to notice when its tail has been bitten. Slowpoke is commonly found at the water's edge. In some places, it is believed that Slowpoke's yawn causes rain. This Pokémon is worshiped in those areas.
In Galar, Slowpoke's appearance is a result of particles being built from eating Galarica seeds. The main difference is that it has gained yellow coloration on its forehead and tail. Unlike its counterpart, its tail is always down and said to have a spicy taste.
Galarian Slowpoke are known to relax on seashores and riverbanks without a care in the world. Occasionally, it will get a very sharp look in its eyes as if it is about to think of something tremendous. However, Slowpoke will quickly forget and return to its normal expression. It is believed that its behavior is a result of Galarica particles affecting its brain.
In A Crowning Achievement, multiple Slowpoke were trying to reach a King's Rock to evolve into Slowking in order to help find a better habitat for the group. In this episode, Alice Telesu's Slowpoke, nicknamed Arthur, evolved into a Slowking when its head was bitten by a Shellder while it was wearing the King's Rock.
Slowpoke, the Dopey Pokémon. A Water and Psychic type. Slowpoke's tail often falls off, but it doesn't hurt, and a new one grows quickly, so the Slowpoke doesn't seem to mind. It takes a little time for them to feel pain.
Giovanni stole Slowpoke from Kurt prior to Find Slowpoke!! in order to profit from its tail as it is worth a lot of money. Kurt was able to retrieve the Slowpoke from Giovanni before Giovanni was able to get its tail.
The Japanese and international versions of Pokémon Silver have different sprites for Slowpoke, with the Japanese versions having a fatter and striped belly similar to that which Slowbro and Slowking sport. It is unknown why this was changed. However, its striped underside is still partially visible in all of its Gold and Crystal sprites. This striped belly does not appear to be a true error, as it has been seen in artwork by Ken Sugimori, though it is from Generation I.
Like Mantyke, Slowpoke evolves when another Pokémon is attached to it; however, this was only seen in the anime. Proximity-based evolution such as requiring Mantyke and Remoraid to be in the same party were not introduced until Generation IV.
Slowpoke is the only Pokémon whose multiple evolutions have different total EV yields: Slowbro has an EV yield of 2, while Slowking has an EV yield of 3.
Despite numerous Pokédex entries stating its lack of response to a bite on its tail, in Pokémon Snap it is shown to quickly react to Shellder's bite. This may be due to Shellder's venom stimulating a quicker response, or simply an error or game mechanic to speed the process along.
The Pokémon Company posted a Slowpoke-themed reggae music video onto their Japanese channel titled What's Going on, Yadon?. The song was later dubbed and posted to the English-language channel under the title of Slowpoke Song.
Though the species has appeared repeatedly, no Slowpoke has ever been seen using an attack in the anime.
Its ability to regenerate its own tail if cut off refers to autotomy.
Slowpoke is literally slowpoke, a term for someone who is slow. It can be also a combination of slow and poke (an abbreviation of Pokémon).
Yadon may be a combination of 宿借り yadokari (hermit crab) and donkan (thickheaded or stolid), whereas 鈍 don means slow, dull, or stupid. Alternatively, it may also derive from 宿主 yadonushi ([parasitic] host), based on its relationship with Shellder in its evolutions.
