>>1839745I'm... gonna take the time to re-rep a previous suggestion I had at the start of the story:
E) Sewaddle
http://bulbapedia.bulbagarden.net/wiki/Sewaddle_%28Pok%C3%A9mon%29I know it's Gen V (and we're sticking with Gens I-IV), but I love the potential for both causing and later on preventing ENF this thing has. Being a little caterpillar the whole "eats holes in Melody's clothes" is easily possible, and the final evolution of it actually makes leaf clothing, which Melody could use if she loses her clothes in the wilderness or something.
...Plus it's part grass and could help with the first two gyms. Just keep it away from fire.
I know it's a bit moot, but still.
