I am loving that there's place to ask questions and I do have one. What is the pink mushroom or top looking icon in the higher levels? I have no idea what they are or how they work and I really struggled with that level which I think was in the 700s to begin with. What does it do?
To get gold bars, you earned them in the races. You got five for first place, 3 for 2nd and 1for 3rd place. That's how you win them for free. Or you can purchase them
