Water You Doing is a Grojband game that is playable on the Grojband Website.
Gameplay
In this game, you must play as Laney and throw water balloons at Trina to ruin her time at the prom, while trying not to throw them at Mellow. Each successful hit on Trina fills her with rage, hit her enough times to make her go into Anger Diary Mode, be quick about it though, as she'll calm down over time (this happens when she's not hit with water balloons and angry), and you also have a time limit. Hit the balloons for more ammo, since the supply is limited.
