mocchi
pichu
They are in veridian forest 2. Usually one random wave of pikachus go during that level.
First, you have to get a Yellow Orb from a scour Next, you have to hatch 6 pichus and evolve them all into pikachus Finally, you have to give each of the 6 pikachus (the ones that you hatched) the yellow orb. (you don't need 6 yellow orbs you just need to take it away from the pikachus) Hope this helped!
