Papa Monkey and Little Monkey are on their way. But the street is very busy and they are going so slowly! Little Monkey loses patience and jumps onto the fire engine. Up the ladder from there and he joins a TV crew! Then the garbage truck, an aquarium bus, a food cart for rabbits packed with carroty treats, Arctic animals traveling by snow globe, a jewel thief's getaway car ... There is so much going on in the street, it's become a playground!
