Sweetpaw:

Sweet: "Rosepaw, let's have a mouse, because I'm hungry!"
Rose: "Okay, sure, even though we haven't caught any fresh-kill."
They chew on the mouse, that was green and smelly, with flys and maggots in it.
Sweetpaw cough and falls on the ground, her tongue pushed to the right by her head falling to the left.
"Oh, no. You died!" Her sister says, completely fine even though she ate it too.

Later that night, Sweetpaw gets buried near Sun Rocks.

Sweetpaw: "cough, cough! Iwm suhhffictn....... Hhhh hhhchgg.." She suffocates and dies.

(Sweetpaw actually did suffocate and die, (thanks @Pure_Awesomeness83 for that fact in your fact book!))
