Help?!?!?!?!???!?!?!?!??!?!?!?…

well, im planning my lil sis bday she is turning 12 in october on the 24th and i dnt know what to do for her bday party? she wants to either go paintballing or indoor skydiving. she is a total daredevil, so shes up to anything. but the only thing is, is tht she wants to go invite all 3 of the 6th gr cles, so she was thinking maybe she could do a pool party on thurs. since we live in AZ, and we have a pretty huge pool, she was thinking maybe bobbing for apples and she doesnt know what else to do other then go to the ginat rock wall gym. she was also thinking have the pool party thingy, and have a couple of her best friends sleepover and the next day go indoor skydiving?but i dnt know what to do. nothing girly or princessy she is disgusted with stuff like tht. umm, and maybe halloween themed. just pitch some ideas, thx so much
