Sunny is writing a book about his favourite vet, but first he needs to ask her questions. Vida lets Sunny tag along on a day of house calls, so she can tell him everything he wants to know - in song!

Sledding, snowball tag... it's a snowy day in Sweetwood! Zigzag's day is almost ruined when she refuses to wear mittens and gets way too cold. Luckily, Vida knows how to warm her up and Popcorn knows how to make cocoa, so together they save the snow day! And Zigzag learns to love mittens.
