Ruff Ruffman, the lovably charismatic host of FETCH!, jumps from screen to page with a pair of readers that combine comical stories with real-life science. Ruff Ruffman is having a bad day. First, his fancy pants get stolen, then he gets a message from his boss that seems to say he’s been fired! There’s only one way for him to find out: visit his boss in Australia. To do this, of course, Ruff turns his doghouse into a "green" vehicle (powered by cooking oil from a Chinese restaurant) and adds pineapples to keep it from sinking. Inspired by this Ruff-and-ready innovation, young readers are invited to create their own tinfoil boats, then load them with pennies to test how well they float.
