Ok... Most people would know this, but for some players, here is a little hint. Unless you have worked out the easier way to get Caterpie into Butterfree with only 1 level of Metapod. But, to make metapod have tackle so his leveling is easier, just do this- When Caterpie/Weedle turns lv. 7 and starts evolving, cancel it. When he/she turns lv. 8, let him evolve. Voila! A metapod/kakuna with Tackle and String Shot!
