i just made a forums account so idk how this works but heres my report:
in gen 5 ou, it says that whimsicott cannot have encore and switcheroo, which is wrong, by breeding first a male cacturn with switcheroo and a female whimsicott, you can get a female cottonee with switcheroo, then you can breed this female cottonee that knows switcheroo with a male togetic that knows encore to get a cottonee with encore and switcheroo, then you can train it to have a whimsicott that knows both encore and switcheroo, i did this in my pokemon white 2 save file so i was confused why it didnt work here when it should
BUG STATUS: NOT A BUG, female Pokemon don't pass down egg moves in Generation V. The only possible father for Switcheroo is the Cacnea line, which cannot itself have Encore; Encore is an event move on Cacnea, it's not an egg move. But Switcheroo is Egg move only on Cacnea, so Cacnea can't have both, which means Whimsicott also can't have both (DaWoblefet)
