This interesting surname is of early medieval English origin, and is one of the many surnames generated by the male given name Philip, itself coming from the Greek Philippos, a compound of philein, to love, and hippos, horse; hence, lover of horses.
Best answer. Besides breeding a Shroomish with Spore that way it has it at level 1, you can just wait until it learns it at level 52 then evolve it. Once evolved take it to the Move Re-learner and have him reteach Mach Punch to Breloom; you will need a Heart Scale to do this method.
Poliwag and Poliwhirl actually learn the rare Amnesia technique at level 38 and 41, respectively -- unfortunately, the Polis' Special stats are so low, using Amnesia doesn't make that much of a difference. Note that Poliwhirl has one more evolution: Poliwrath , a dual Water/Fighting type. Because of its mediocre stats, I would use Poliwhirl only against Fire, Ground or Rock Pokemon -- the three types that are susceptible to Water attacks.
