In the Water Sons game, Gumball had enough of the sunniest day in years. At first, they had a peaceful mindset, but soon the sun rays became even hotter and more annoying. Now the town of Elmore is sunk in a fiery heat, and people hardly bear it. This girded situation calls for the Wattersons!

They loaded their trunks with water balls and rocks, but they can't win alone. Combine your forces and help Gumball to cool off their friends. Aim properly, think fast, and prepare for a very wet battle against the sun!
