I'm all for it, as someone who's been experimenting with music in his writing over this last year. Twisting their song on its head was quick and canny, and I dig it.
Both rabbits who were by the snail, were startled by the arrow from Aurora, and the other rabbit tries to get the snail to leave with the rest of the Brigands.
"Come. ON! Let's go you stupid---!"
The snail refuses to budge and simply lets out a louder angry noise at the brigands.
The brigand recoils before he sneers "Fine! Stay if you wanna be escargot so damn much, you stupid thing!"
He then runs away as well.
Brigand D tries to bring the snail along. Animal Handling at disadvantage is a 4 so that's a no.
A spiked magic missile is nasty. The spell scales up well to higher level slots too; just not for wide target damage. Zavakri had no idea what these rabbit bandits were capable of so she just sniped their leader.
