Level 1-IX is a bonus level in Ground Hog Day. It is unlocked by collecting a combined total of 12 stars in the levels 1-33, 1-34, 1-35, and 1-36.
The player is given a 4x3 grid, along with the following parts:
- 1x Ross
- 4x Wooden Frame
- 4x Metal Frame
- 2x Metal Wheel
- 2x Powered Wheel
- 2x V8 Engine
- 2x Electric Umbrella
- 1x Spring
- 1x TNT
The player is awarded stars for the following conditions:
- Ross reaches the goal.
- The level's Star Box is collected.
- The level is completed within 10 seconds.
To fulfill the time condition, build a simple metal cart, replace the rightmost Metal Wheel with a Powered Wheel and move it to the side of the cart, and fill the remaining spaces with V8 Engines. Then, just turn the wheels on and let the cart drive all the way to the goal.
As for the Star Box, create a 4x2 cart with a Powered Wheel as the front wheel, place two V8 Engines at the back, and place Ross at the front. This time, you'll want to take the bottom path; then, when the path splits again, take the bottom path once more. Once the cart lands on the ground after this, speed up as much as possible so that you make the jump up to the top path, then go through the loop and collect the Star Box before going to the goal.
