World 6 - Level 3
Stinky's Solo Adventure
Make sure to "rescue" one steel box in the direction of the green arrow. Move it aside (e.g. to the green "X"). Drop the two wood boxes in the water, this will create four more. Drop the right and lower box in the water, use the yellow boulder to destroy the left box, then drop the top box in the water. Four more are created. Push the top box left and destroy both that and the left box using the red boulder (use the steel box as a stopper). Drop the remaining two wood boxes into the water, creating four more - two more are used for the final bridges. To get the Bonus Coins, roll one boulder into the conveyor belt and follow pushing a steel box. The boulder will activate one conveyor button, use the steel box for the other.
