So as of this point, Raticate is the biggest change in my 'Alter evolutions to match the previous stages a bit more' policy (as I still leer at Pigeotto who I need to tweek). While I didn't make them a purple fluffy lump like Ratata is, there are more hints of purple into their brown fur and the color change is a little less stark. I also shifted the anatomy to be somewhat similar (in terms of 'actually has legs) and changed their eyes to match the previous stage.

A bit of a nitpicker? Yeah.
