Guide for making pokemon in Rumble wobbly:Another alternative is False Swipe, though not as many Pokémon can learn that. I -think- Pain Split is also an option, though I've never used it before.
-Teach a pokemon the Endeavor move (4* normal, grass type pokemon can learn it for sure)
-Make sure the area is clear of other enemies
-Beat the target up
-Keep spamming Endeavor (for bosses, do it when they try to rest) (it will take only 1 hp so you can almost kill the boss and spam it)
-Eventually you'll make the target wobbly, then use any other attack to finish it
-Enjoy your pokemon
