Level 1-15 is a level in Ground Hog Day. It introduces the use of Soda Bottles to directly propel a vehicle into the air.
The player is given a 3x3 grid, along with the following parts:
- 1x Ross
- 3x Wooden Frame
- 1x Wooden Wheel
- 4x Black Soda Bottle
- 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 without using TNT.
Even with TNT, it is very difficult to reach the Star Box and get to the goal, as doing so would require detonating the TNT at a very precise angle. However, there's a solution that collects the Star Box without using TNT at all: Placing three boxes in a row in the middle of the grid, placing Ross in the rightmost box, then filling the bottom row of the grid (and the space above Ross) with Soda Bottles pointing towards the ground. From there, all the player has to do is activate the Soda Bottles.
