Scaredy shroom pvz 2 international

I have a theory is to why scaredy shroom looks the way he does in pvz 2. So I think he was tired of being scared of the zombies and wanted to make it so that he could face his fears, so he got plastic surgery to make him look scarier but the process was a big failure and he thought it was hopeless so he continues to be scared of the zombies in pvz 2.
