whats a shiney/shinny pokemon?
A shiny Pokemon is a Pokemon that is a different colour to the 'normal' one. They're really rare, the chances of finding one are 1 in 8192.
As an example:
Normal gyarados
Shiny gyarados
And...
Normal charizard:
Shiny Charizard:
(See
Normal sprites and
shiny sprites here, for FireRed/LeafGreen)
and "slave pokemon for rock smashes" - are they just in your team but never used in battle? - doesn't that take up a valuable place in the crew? im guessing you dont teach the smash move to a valued member so they can keep a handy attack in their armory?
