Game currently lacks unique death animations like zombies getting charred/zapped

Every zombie dies in the exact same way, and its really very boring. Both prior games are filled with zombies having a lot of varied death animations, the same should go for this one, especially seeing as how this game includes plants like lightning reed, cherry bomb and jalapeno. Seeing as how there were effort put into the animations for plants initially being planted, its odd there's not a lot for the zombies either.
