Witzy is pushing his toy train around a track in the sand—“toot-toot!” When Boof asks if he can have a turn, Witzy tells him, ”Not now.” Boof can only watch. Meanwhile, along come the twin turtles Teeter and Totter with Peekaboo the snail. They see the sand mountain, and try to climb atop it, but end up tunneling through it instead. Witzy and Boof are so surprised by the turtle “train” that tunneled through the mountain!
