It's a snowy day and Danny arrives at school to find the place deserted except for his least favourite teacher. Both head outside, where to Danny's surprise Mr Trapper steps in to help build a whole army of snowmen. Together, they have an afternoon of fun, but it is detention as usual when everyone returns to school - or so Danny thinks until he finds Mr Trapper has other ideas.
