Gyrosphere Valley - Gyrosphere Chase
You need to hit three signs during the chase to get the minikit, and as there are only three along the route, stay frosty. There's also an amber fossil to grab.
The chase will begin from a side-on view. As soon as it rotates around to a front-on angle, scoot over to the right and roll over the sign.
After you pass under the monorail track for the second time, you'll start heading down a dirt road. Once you roll by the Compys, swing over to the left. There are four lots of foliage you'll crash through before you hit the sign. As long as you're lined up with the plants, you should hit it without a problem.
The chase will resume a side-on view for a short while before reaching a bend and tailing the action from behind. The sign is on the left side of the bend. Keep to where the mud meets the grass and you'll smash right through it
Amber Fossil (Ankylosaurus)
After the second sign, you'll get a side-on view of the chase. Stick to the area further from the camera to make sure you're on the high ground when the paths diverge. The first upper path has coins to collect, while the second one has an amber fossil at the end.
