All you have to do is make one of the bee enemies kill another bee. I got this during the Wrigglemania challenge where there are four bees in round 3. What I did was spin one bee to make it dizzy and run towards the bees just opposite of him, by being close to the other bee it will fire its stinger directly at me to which I jumped over it and it kill the stunned bee.
*I should note that I didn't test this achievement during the base game. I'm assuming it does work as long as you purchased the Guardian's Trial DLC, but if anyone wants to attempt it the please go ahead and leave your response
