Tonton Streaming Blue's Clues (1996) S1E3 - Mailbox's Birthday

For Mailbox's birthday, there's a special celebration and we're invited to help out. We help decorate the cake for the party by observing patterns. We also skiddoo along with Steve and Blue into a present store. There, we find the perfect present for Mailbox and then help Blue and Steve to find it when it gets lost among a bunch of other presents.
