I think we needed a palette cleanser after the serious stuff, so here's this. Before you ask, I am serious about not making Ice-Shroom, I'm not that confident in my abilities (maybe I'll prove myself wrong, but don't expect it. If you want to take a crack at it, I've included a render I personally recommend to use for a vector. I did actually find a way to make Hypno-Shroom, and while I do think she could have turned out better, I'm still glad I managed to make her decently enough. Gloom-Shroom was the easiest since I just had to use Gloom Birdo, modify it, and I was done. I made Doom-Shroom shortly after posting the Scaredy-Shroom vector, and frankly he was one of the easier plants to recreate for obvious reasons.
Assets used to make Hypno-Shroom, Doom-Shroom, and Gloom-Shroom (including Gloom Birdo) by @Scribbleslol102. The music was from a PvZ2 Pak. I fully admit, I had a phase a few years back where I played PvZ2 Paks religiously, and nowadays I'm burnt out on playing PvZ1 despite it being my favourite game in the franchise.
