It's Valentine's Day, and Danny has bought D.J. the royal blue sweater that she wanted. When she wears it to school, at recess, she takes the sweater off so she won't sweat all over it, and the school's gardener runs over it with a lawn mower. D.J. doesn't want Danny to know about this, so she, Kimmy, and Stephanie go to the mall to buy a replacement sweater.
