Skimming Tip Serve

From SlimeWiki

The Skimming Tip Serve is another variation of the Tip Serve. A replay of it is below. This serve is useful when playing the Big Blue Boss. I have only won two points against the BBB so far, and both of them have been when I aced him with the Skimming Tip Serve. To perform this serve, let the ball bounce on your slime. Then, while the ball is rising, move towards the net a little, jump straight up, and then move backwards into the ball to hit it against the ball. After the ball bounces off of the wall behind you, position yourself so that it bounces on the top-front of your slime and skims just over the net. If this is done perfectly against BBB, he will jump over the ball and you will ace him! Unfortunately, it is hard to do this serve with consistence.

This variation's helpful when you're against a real opponent:
