you could use: on click on sprite"Apple": spawn sprite "Apple" at point x,y (and the same for the other member)
or
add instance text variable to your "Fruit_Family" (eg "type") and set the instance var "type"= "Apple" for apple sprite, "type" ="Orange" for orange sprite etc
on click on Fruit_Family
---Fruit_Family.type="Apple": spawn sprite apple at point x,y
---Fruit_Family.type="Orange": spawn sprite Orange at point x,y
--- etc
or you can play with the rex nickname plugin
