What about:

You are fighting the Great Buffalo. When you kill it he drops dead on the ground for like 10-15 seconds, then thanks to a system of death despawning that gives an explosion power compared to the monster's bigness, the Great Buffalo EXPLODES KILLING MONSTERS AND PLAYERS ALL AROUND HIM SO WHEN THE OTHER TOXIC TOADS EXPLODE THEY DO A [SIZE=5]TOXIC BOMB ATTACK![/SIZE]
oh, and once they explode they release a Toxic Gas that will Spread into La Noscea KILLING EVERYONE THAT IS ON THAT [SIZE=5]RANGE[/SIZE][SIZE=5]!

Nah, to be serious, if they have to change that (and they don't need to), then transform them into little wisps that disappear on the sky.
