Turbo Super Stunt Squad

Custom shells are unlocked by picking up the character pickups. The character pickups look like a set of tokens with the picture of the racer you're using. There's a set of 5 pickups for each racer on each level. That means there's 6 sets for each racer. You need to pick up all 5 tokens in one attempt on a level. You'll unlock a custom shell for a character when you pick up the sets on 3 different levels. There's a second custom shell you unlock when you pick up another 2 or 3 sets. (someone please confirm if it is 5 or 6 character pickup sets needed to unlock all custom shells for a character; I unlocked this achievement after picking up only 5 sets with my last racer). So you'll need to unlock two custom shells for each racer (5 racers total) to get the achievement. Please leave your questions and comments below and give me a thumbs up if I helped you out.
