1. Go to the right side and free the ladybugs by smashing the red block while moving down.
2. Bounce off the lower red block and move up again. Go next to the cacti so that the ladybug can destroy one. You better use THRUST to be fast enough. The first ladybug will walk up and eat a cactus. Meanwhile you dig down on the left and go to the position shown in the next picture.
3. Now move to the right past the cacti. The second bug will walk to a cactus and eat it, if you made the path right.
