here's the tree that could be shaken to get prizes. one shake cost one gingrrbread. the first 5 were given for free.
attack level 8 and above npcs to get gingerbreads. usually get 1...
if lucky enough can get two! after the fifth time obtaining the gingerbreads from these attacks, u hv to use alliance signets to obtain more.
crazy shake can be activated if u hv an elf. get one elf after 50 gingerbreads are used though. crazy shake is said to give better prizes. for example, the above image shows that I got erosion sanies, a sunstance that can be turned into suicidal corrosive worms, but it is better to get them with corrosive larvaes.for me, it is better if I obtain 150 Gems (top left) or that 12000 demon souls (top right).
