Night Lights - Nick and Sally are making shadow puppets with the Cat in the Hat, but the batteries in the flashlight have gone out! They jump into the Thingamajigger and shrink down to visit the fireflies that live in the backyard. There they learn that the fireflies communicate by flashing their lights. And when the fireflies provide the light the kids need, the shadow puppet show can continue! Go Snails Go! - Nick, Sally and the Cat have been invited along on a snail expedition! They jump into the Thingamajigger and shrink down to meet up with Lewis and Clark, the two snails leading the way! As they travel through the forest of Slippity-Goo, having fun sliding in their own shells, the kids learn about all the different ways snails use their shells.
