According to a recent study by Professor Cedar, Vaporeon has the capability undergo variant evolutions tied to its environment.
This is speculated to be due to the highly volatile nature of Eevee DNA and the evolutionary tactic of extreme adaptability all Eevee possess. To adapt expertly to climate and environment upon evolution, the pre-evolution Eevee will adopt aspects of other residing species of pokemon, ensuring an incredibly high survival rate.
The standard Vaporeon variant occurs if the Eevee has not resided in a particular environment for an extended time, or in heavily populated human city centres.
To Sua Ocean Trench is arguably one of the most scenic swimming locations in the world. This unique land formation consists of two large holes which are joined via a lava tube cave. The water is 30 metres deep and can be accessed by a ladder.

Dwarf Cleric: I throw my shield, Captain America style.
Me GM: Ok.
(rolls nat 1)
Me: You throw your shield into the river.
Dwarf: What river?
Me: That one. (Points to map)
He bought another shield.
Dwarf: I throw my shield at a random guy.
Me: (Rolls to determine target.)(Target is himself. Rolls nat 20. To shake things up, I roll on the something happens table. “An old enemy returns…” is what I got.
Me: Holy shit. So…you throw your shield, it curves round, and conks you on the skull. (Rolls max damage possible)
Dwarf: At least I still have my shield.
Me: A river comes crashing down the mountain, and sweeps away your shield. As it fades away, you can see your other shield in the river.
Dwarf: I fight the river.
Me: (rolls nat 1)
Me: The river forms a water elemental, and the water elemental takes both of your shields…
Me: (rolls two nat 20s)
Me: WHAT THE ACTUAL FUCK! THIS ELEMENTAL SLAPS YOU AROUND WITH BOTH OF YOUR SHIELDS UNTIL YOU ARE UNCONSCIOUS, AND THEN LEAVES.
Bard: I loot him
