If you are having trouble surviving in the later areas you can slow your self down a little with the wingsuit, or you could even switch to Maya for this one. Survive for 2 days straight - For this you have to survive 15 minutes, unfortunately idling in the menu will not work for this challenge.

Smash 3 rocks with one boost - Same as level 53, travel as far as you can, land a combo, smash rocks.Pick up a coin magnet 4 times in one run - This unlocked after picking up only 2 magnets for me, most of the magnets are found on ground level or after ramps.Rip 500 bunting flags in once run Level 55.Score 10,000 points in the first 3,000m.Collect 10 super coins in one run - The coin magnet powerup will help a lot here.You should aim to do this on your jump 15 chasms run, simply land a trick or cross an ice patch and hope to smash into some rocks. Rocks appear more often the further you go. Smash 3 rocks in 10 seconds - Similar to Paz, Tupa has an increased sonic boom.Land 75 backflips in one run - Pretty simple, Tupa can double jump which means you can get a backflip pretty much anywhere, simply double jump backflip and repeat, I don't think double/triple backflips count as extra backflips so keep it simple.Wingsuit to rock bounce - Glide close to the ground in the wingsuit, when you come across a rock fly towards it and cancel your wingsuit, if done correctly you will bounce off the rock.Escape 5 elders in one run – The 5th elder appears around the 19,500m mark Level 52.Fall into 1 chasm as Tupa - This will demonstrate Tupa's extra life ability, simply jump into the first chasm you come across and you will respawn at the other side, you only get 1 extra life per run so in the future use it wisely.
