After finally accepting my Tentacool it sadly passed away in a tragic storm...
I was rushing through a heavy storm only to realise an hour after arriving home that my Pokewalker had separated from it's backing.
Leaving my poor little Tentacool washed away. After the rain had stopped I re-traced my steps but it was gone.
If I could I'd make a memorial @ Lavender Town.
I never got to name it either. Note to self: Don't take Pokemon for a walk during a heavy storm. :(
