Level 1-III is a bonus level in Ground Hog Day. It is unlocked by collecting a combined total of 8 stars in the levels 1-9, 1-10, 1-11, and 1-12.
The player is given a 7x3 grid, along with the following parts:
- 1x Ross
- 1x King Pig
- 6x Wooden Frame
- 3x Wooden Wheel
- 4x Black Soda Bottle
- 4x Green Soda Bottle
The player is awarded stars for the following conditions:
- Ross reaches the goal.
- The level's Star Box is collected.
- Ross reaches the goal with King Pig.
To collect the third star, you'll need a 5x2 cart with King Pig occupying the three frames at the front, an extra wheel in the middle, and three of each type of Soda Bottle placed on every remaining open space, facing left. With King Pig in tow, the cart will be too heavy to make the jump necessary to get the Star Box, so you're better off taking the lower paths. You will need the Soda Bottles to give the cart that extra push needed to get past the inclines at the ends of these paths; they should be activated once the cart has gone about half of the way down each hill.
When going for the Star Box, you can create a simple cart and put two Soda Bottles on it, both facing left once again. The first top path is entirely unnecessary, and you can just take the bottom path; your cart will be light enough to make it past this path without help. The Star Box is located on the second top path; to reach it, activate the Soda Bottles once the cart reaches the last patch of thin grass before the path splits. From there, the cart will collect the Star Box and roll to the goal.
The cave below the starting platform contains a Skull. Place two Wooden Frames on top of each other, place two Soda Bottles on the sides of the bottom frame, place a Wooden Wheel on the right side of the top frame, place Ross on the other side of the top frame, and move the contraption to the bottom-right corner of the grid. From there, simply fire the Soda Bottles and Ross will be thrown into the hole, eventually rolling all the way down and collecting the Skull.
- King Pig is normally introduced in Level 1-25.
