Picky Peck has no animation, Silvervine Stem Spear has that weed being thrown. The one i'm referring to is magic.
I could be wrong but I think there's a teardrop/ghost bullet animation for Picky Peck which according to the description is "the souls of Pickys being fired at the enemy." Poor birdies.
Havent found the gears that boost SV stem spear yet, for it to be used over Picky Peck(with an easy 6000% chance to 12000%), must be good.
I believe Silvervine builds use this branch accessory, reduces casting time and increases damage:
