Sandy Tracks
Sandy the Bulldozer joins Zack and Lily for a game of hide-and-seek. Zack and Lily are very surprised at how good Sandy is at hiding. But they soon discover Sandy's tracks, which they hope to follow to her hiding spot. When the tracks go over a rock they figure out to search the other side of the rock to find them again. When the tracks go into tall grass they learn to look for grass that's pushed over, and when they encounter tracks all over the place they search for other clues in order to find Sandy.
