I'm thinking of a Pokemon that.....

[treecko_332]

nope

 

[Spectreon]

Gloom? Same reason as before with Poliwhirl

 

[killa_project]

maybe it's clampearl. It has two different evolutions.

 

[Eevee234]

Eevee? 2 evolutions depending on time of day.

 

[penguin_master]

Moltres?

 

[SwampertEX]

Just FYI is has to be a R/S pokemon. Read the rules on the first page.

 

[liminy0]

Duskull
It is ghost type.. :`( well, kind of mysterious.
It is one of the amorphous breeding group.
It has a head like a heart with two holes on it.

Is the second clue "CATTERPILLER"?

 

[treecko_332]

none to all, and swampert it doesn't have to be a r/s pokemon. It can be. Needless to say. Oh yes, no more clues.

 

[liminy0]

Is it catterpiller or caterpiller?
Anyway, I guess Umbreon.

 

[Eevee234]

Nidoran(Male)?

 

[liminy0]

Eevee

 

[treecko_332]

nope to all

 

[penguin_master]

Delcatty?

 

[treecko_332]

no-ope
