Molly and Gil went to explore the surrounding area Babbltaki and swam so far, that now do not know how to get home. On the way, they come across a great big fish, Mr. Gupper, kiddies who can provide the service and show them the way to the house with the only condition that the guppies will find it for hidden numbers. Rather help Gil and Molly find the numbers that are located throughout the submarine part of the ocean. The ystree they do - that are likely to be at home in the embrace of their beloved sisters.
