halloween help needed

when we went home daddy found the cutest little spider costume for only $5 at the goodwill so i just had to have it. and we decided that since we are having the party on Saturday and Halloween is actually on Sunday we can dress her up both days. the problem now is that daddy and mommy don't have costumes for the big party. we would like to do a big family theme but i am having a hard time putting and idea together and collecting all the materials for one costume nor less three...ugh. thank goodness i still have some time to work it out.
