If you must handle a Toxel, do so very carefully. Wear rubber gloves and wash your hands after touching anything this Pokémon has touched. Toxel secretes a poison from it’s skin, and while it’s not known to be deadly, there’s always the chance of your skin reacting to it’s toxins.
Toxtricity is very picky about the water it drinks. This Pokémon will actively refuse to drink flowing water, as it gains much of it’s toxins from drinking out of stagnant pools.
