Do a Sweet Jump is the fourth level of Meet Swampy.
There are two versions of this level; one is an older version, while one is newer.
To beat the older version, simply start from where the water is and dig straight down through the dirt on the left side, then quickly uncover the dirt at the end of the path. This will act as a ramp, which the water will travel on. When it reaches the end, it will fly over the gap, collect the ducks and go into Swampy's shower pipe.
The new version is essentially the same, except the player needs to make their own path through the dirt instead of having preset paths.
