I don't really know what to say here, but I will say that all plants gotta be animated at some point, and here's a few of my picks. Some plants from older projects still don't have animations either, so I've picked Tangerine Mortar from one of Perickles2's projects. Press 1 for Seedling's animations, 2 for Tangerine Mortar's, and 3 for Scaredy-shroom's. I thought his third style looked the best. It's also pretty cool that we're getting plants from PvZ Heroes in this game. In my opinion, Bananasaurus Rex could translate pretty well into Tower Defense form, so maybe she can make a debut one day. Tangerine Mortar's animations are fine, but I think they could be better.
The projects I got the vectors from are by @mjgame2020 and @Perickles2. The PvZ IP also belongs to Popcap and EA. The Tangerine Mortar plant belongs to @INSANITY_SANS_. The music in this project are composed by Becky Allen and Barry Dowsett, and Yoko Shimomoura. The music from Bloo Kid is likely from Winterworks, since he might've made the game by himself, which means he might've composed the music, too.
