Kex & Kola are two hamsters living in Hamster Valley in the sewer. The sewer is no longer what it once used to be as it is clean, with rivers, crystal clear waters and palm trees looking like a tropical paradise occupied by Hamsters that are middle and upper class. Follow Kex & Kola into a magical sewer in a book written for those who like to dream. From adventures of playing soccer by the crystal-clear stream with Vincent who is a colorful turtle morph and a product of the pet trade, to dreams of one day making it to the rodent's champions league. Kex & Kola teach children about the importance of a good oral hygiene using a fun and entertaining theme. With the toothpaste and fluoride song, toothbrushing is always fun and something that every child should look forward to, twice a day. In a story never before told from below a magical lid, children are thought how to properly brush their teeth with circular movements. A fun saga and an entertaining journey into the sewer in a way that the sewer has never been portrayed before. A magical city built by rodents below a metal lid.
