In the opening scene, players discover they are a brilliant little boy who has invented a time machine that works only if big Caterpillar construction equipment is used to activate a time vortex. Upon arriving in a chosen time, players are given a quest, which always involves helping to build or fix something. For example, when players travel to medieval times, they find King Arthur's castle under siege. To help save the castle, they must destroy the attacking siege tower and then use stones from the tower to rebuild the castle. By driving the backhoe, players are able to collect rocks to catapult.
Players arm the catapult, aim and then fire on the siege tower.
Once the tower is demolished, players can use the heavy loader to move stones to the castle. Girls get to play with Ariel and her daughter, Melody, in five activities. Two of the activities are arcade-style games. In one, Melody dives into the sea in search of gems to make bracelets, necklaces and the like. The other three activities focus on creativity.
