>>28241740The swimming arguement doesn't work as an excuse when there is another gimmick that can explain a typing.
Why is Volcanion water? Because it is the steam pokémon, and together with heat (fire), water makes steam.
Why is Vaporeon water? Because it's a cat with a siren tail and it's a play on the "catfish" word.
Why is Keldeo water? Because it's based on a Kelpie, a demon which is said to infest lakes.
Why is Crabrawler not water? Because it's a fucking coconut crab and it can't swim.
If you want a Water crab, get a Kingler. or a Clauncher.
If you want a water fighting mon, get a Poliwhirl.
Crabrawler is pure fighting. Deal with it.
