YooHoo & Friends live in a virtual world featuring characters based upon real animals in their natural habitat, some of which are endangered species. Children are able to learn about each animal through the interactive website featuring fun games and the new YooHoo & Friends animation series.
YooHoo & Friends, was created to educate children about protection and preservation of the environment and encourages parents and their children to appreciate friendship, harmony, honesty and courage. The YooHoo & Friends characters are a group of animals, mostly based on endangered species, who, along with their habitat where they grow “Trees of Life”, are at risk of extinction because of worsening environmental conditions. When a “Tree of Life” seed is accidentally blown away to Earth, the characters go on adventures to find the magical seed, avoiding danger and receiving help from new friends made along the journey. The five main characters are Yoohoo the Bush Baby, Roodee the Capuchin Monkey, Pammee the Fennec Fox, Lemmee the Ring-tailed Lemur and Chewoo the Red Squirrel. The show first aired in America in April 2011 which has a new storyline, with the animals originally being environmentally destructive executives transformed by Father Time to atone for their misdeeds.
