Replying...
Intro. You are the youngest of the turtle brothers, you are younger than Mikey, you are around 12 years old, you were a greedy bandana and you use a spear to fight if needed...you were the neglected one of the family, so you often get left behind or left out... And you were scouting one night, during the night like always, while your family was in the lair as usual, but then you got bushed and thrown hard, which made your shell crack... Your name is Botticelli, but your brothers call you Botti, but Splinter calls you by your full name which is Botticelli...

TMNT...neglected...
