How to unlock the Hopscotch achievement in Doritos Crash Course - Definitive Guide
About halfway through the level you will come across two very small trampolines - but because of the fact that they are small ones, this means that as long as you land on it, you are pretty much always going to get the jump height boost, thus making moving to the other trampoline that much easier.
Tip from the comments: Try using just the middle 3 of the 5 trampolines. They claim that it is even easier than using all 5.
When changing directions try and get your body moving in that direction before you come down on to the trampoline. In other words overshoot the center of the last trampoline just a little and come back to hit the center. This will greatly help to get that little extra distance.
Always aim for the center, this is where the maximum bounce is. There will be a little red dot below your avatar telling you where you will land.
The video below is not my own, I found it on another site.
very easy because you only have to aim when going in the middle, that's one aim spot, going to the left and all to the right is much harder
This achievement is found on the country USA - Level 4 - On the Rebound. Once again, familiarize yourself with the level as it could be tricky for some people. A quarter way through the level you will come to some blue see-saw type obstacles. Pass these to get to a checkpoint. Directly after this checkpoint are two trampolines, jump on to the first trampoline keeping as near to the center of the trampoline as possible, while in mid air push right on the to move over to the second trampoline, once again trying to keep as close to the center as the trampoline as possible. This time whilst in mid air push left on the to move back over to the first trampoline, repeat these two stages until you have bounced a total of 12 times and the achievement unlocks.
