I just imagined this:
btw these are made-up characters and aren't in the series
Foxpaw(med) - Alright got some catmint for Dirtsnout's greencough!
(It's death berries)
Foxpaw - Here you go! Some catmint!
Dirtsnout - Uh, that doesn't look like catmin-
Foxpaw - It is, tho
Dirtsnout - uhhhhh...ok?
Foxpaw - well, go on, eat it.
Dirtsnout - but they're death berries...
Foxpaw - no
Dirtsnout - Y-you're the boss...
*eats 'em* *immediately dies*
Foxpaw - oh
