Some kind of facts (I'm retired from Shuttle): Future Bubu Seed's animation is 2x faster compared to older versions, therefore leading to audio delay and attack speed don't match with the animation (Also it doesn't made by any shuttle artist as it came from a chinese game called SEERS btw)
fun fact rotten red was a plant added to pvz2 china for a make a wish kid it was removed because the devs was not above to do it if you got it in the short time that it was available you will still keep it and can still use it (someone at the pvz2 china dev team was likely fired)
