Balloon Friends

One day, little balls decided to play a game, they gathered in a clearing and started rolling towards each other. The first ball was green, the second was pink, the third was red, and the fourth was blue. When they gathered, they began to work together to create a new kind of unique ball.
The goal of the game is to create a perfect ball by connecting other balls together. The bigger the ball, the higher your chance of success!
With your persistence and ingenuity, can you be the first to create a perfect ball using fusion?
