Tentacool
The Jellyfish Pokémon
Type: Water/Poison
Official Registration #: 72
Entry: A jellyfish pokémon endemic to the seas of practically every region. The tentacle-like stingers of this pokémon can reach lengths of up to 120 feet, depending on the specific subspecies of tentacool. However, each subspecies has its own average length, making determining the size of the average tentacool rather difficult. What is shared between all subspecies of tentacool, however, is what each of them use their stingers for: ensnaring literal prey … as well as ensnaring metaphorical prey in exactly the way the Sinnohan administrator thinks, for once. It is thus not recommended to bathe with your tame tentacool—which is strangely a warning that has been deemed necessary to share, thanks to certain incidents within the Pokémon Fan Club.
Tentacruel
The Jellyfish Pokémon
Type: Water/Poison
Official Registration #: 73
Entry: The evolved form of tentacool, by battle experience. Because it possesses over eighty tentacles, tentacruel pares down its limbs to avoid knotting, unlike its preevolved form. None of that prior sentence is a euphemism, oddly enough, but saying it enjoys whipping and ensnaring potential prey … can be. Do not bathe with this pokémon either.
