Here's the plot of the challenge:   While doing some training alone in the bat cave, a 12-13 year old Robin (whether is Dick Grayson or Tim Drake is up to you) accidentally knocks over a table with chemicals from Poison Ivy that Batman was experimenting with, causing one of the chemicals to fall on him. The chemical causes him to become unconscious for a while.   When he wakes up, he's called by Batman, who tells him that the Joker and his gang are robbing one of the ban
