I've received tons of questions about the character roster, karts, time trials, online matches, and more for Nickelodeon Kart Racers 3: Slime Speedway so I decided to make my own unlockables guide to discuss how to unlock everything! Below are all the timestamps for each hidden character/item to help you!
NOTE: Some characters and other stuff will already be unlocked plus other things not mentioned are available for purchase using slime tokens in the garage!
