is moose a part of Family1? because if so your code is telling it that on collision with moose to subtract 1 from lives.
maybe add two collision boxes to each (both the player's ball and the moose) to differentiate where the collision takes place, so you have a box for player's feet (or bottom of ball) and a box that represents "top/front/back" of player, and then a box that represents the "top" of the moose and another that covers the "bottom/front/back".
then set it so if player's "bottom" collides with moose "top", destroy moose, add whatever to points
BUT
if player's "top/front/back" collides with moose "bottom/front/back" then subtract 1 from lives
