#32 Nidoran Male

Height - 1'-08"                     Weight - 20.0lb                     Type - Poison Pin

Stiffens its ears to sense danger.  The larger its horns, the more powerful its secreted venom.

I think these can be found west of Viridian, I found mine in the Safari Zone.  I'm not sure about red or blue though.  It looks kind of like a scaly rabbit.
