Randy's Homophone

The other day, Rachel cut her finger and needed a bandage. Randy said that he would get her a "mini bandage" because her regular ones are too big for that spot on her finger. Rachel got very excited about this "mini" bandage. When Randy produced the brown mini bandage, Rachel bursted out crying, "You promised me a 'Minnie' bandage. This is brown...not 'Minnie'!!!" How do you explain a homophone to a three year old????
