Flegmon

Red / Blue: Incredibly slow and dopey. It takes 5 seconds for it to feel pain when under attack.

Yellow +2: Incredibly slow and sluggish. It is quite content to loll about without worrying about the time.

Gold: It lazes vacantly near water. If something bites its tail, it won't even notice for a whole day.

Silver: A sweet sap leaks from its tail's tip. Although not nutritious, the tail is pleasant to chew on.

Crystal: It is always so absent-minded that it won't react, even if its flavorful tail is bitten.

Ruby / Sapphire: SLOWPOKE uses its tail to catch prey by dipping it in water at the side of a river. However, this POKéMON often forgets what it’s doing and often spends entire days just loafing at water’s edge.

Emerald: It catches prey by dipping its tail in water at the side of a river. But it often forgets what it is doing and spends entire days just loafing at water’s edge.

FireRed / X: It is always vacantly lost in thought, but no one knows what it is thinking about. It is good at fishing with its tail.

Sun: Its long tail often breaks off. It doesn’t really feel any pain, though, and the tail grows back, so Slowpoke isn’t particularly bothered.

Moon: Alolan home cooking involves drying Slowpoke tails and then simmering them into a salty stew.

Ultra Sun: There are some places where Slowpoke is worshiped because of a long-standing belief that whenever Slowpoke yawns, it rains.

Ultra Moon: Although their tails, which fall off naturally, can easily be found lying around, they’re a precious ingredient for cooking.

Sword: Slow-witted and oblivious, this Pokémon won’t feel any pain if its tail gets eaten. It won’t notice when its tail grows back, either.

Shield: When this Pokémon’s tail is soaked in water, sweetness seeps from it. Slowpoke uses this trait to lure in and fish up other Pokémon.
