This Achievement is normally done by Finding the Elusive Purple Tree but it is reversed with the Achievement :
To Unlock this Achievement you need to complete the Level "the Fallen Kingdom" which is part of the Story in under 10 Minutes.
This can also be done with Assist Mode active like all the other Achievements in the game which makes it a Ton easier then it might be without Assist mode.
To activate Assist mode simply Press start and go to settings then go to Assist Mode there have multiple options that can be selected.
Hope it helps, Cheers Guys
