I watched it a long time ago, All I remember is that it's cartoon and these people where going Sledding or Skiing (I think sledding) and this girl (or guy, think it was a girl) went down down the hill and as he went down it, snow falls off the sign revealing a no sledding (or no skiing sign). She meets this old lady who lives in a house or cabin and by nighttime, the girl's parents are about to call the police but just a they pick up the phone she is home.

I haven't seen this in like 10 years or more.
