Throwing toys? Are they like smaller critters carrying bottles? It sounds like you're fighting the Grim Keeper. They're a bit finicky, remember how you beat that hoodlum in the Fairy Council hiding behind that Globox shield? It's a similar principle, you wanna have it so they keep blocking your punches to one side that will leave them open on the other.
It'll take a bit of trying, especially cause the little Grims will keep you distracted so you need to punch them so they don't make contact with you at the same time. Just be relentless and keep the curving of punches technique in mind and you'll get there.
EDIT: Also protip. While double-posting is frowned on, if you wanna add something to a new post but also want it to draw attention, copy-paste the old post and delete it. Make a new post with the old posts contents and add your edit in there, that way it won't break the double-post rule and it'll also be flagged as a new post so someone can better come across it.
