Wamy Water periodically fires a conical splash of water in the aimed direction, damaging and knocking back all targets hit (provided that they are not immune to knockback).
Wamy Water references two memes associated with Hololive 5th Generation member Yukihana Lamy popularized by her genmate Momosuzu Nene.
Wamy is a reference to the specific way Nene would sometimes said Lamy's name which would later become a popular nickname.[1]
"Lamy Water" a fictional product originally coined by Nene after she goes into a full appreciation tangent about Lamy's armpit before hatching a plan to sell water poured through said armpit to peddles to Lamy's fans.[2]. Lamy herself would later create a mock-up of said product while claiming that Nene was selling illegal counterfeit that use Nene's armpit sweat while hers was the genuine one that contain actual Lamy Essence (but also does not contain any Lamy Armpit Sweat either).[3] Said mockup is the basis for the icon for HoloCure's Wamy Water.
Hololive would later release a blue colored lime soda as part of their collaboration with the convenience store chain Lawson. Since Lamy was one of the members that is featured on the label, this meant Lamy Water was a semi-official product.[4]
