TV-Series 1968-1970
"Wacky Races" was created in response to the rather violent adventure/superhero cartoons of the previous two seasons, and even upon its premiere, it was blackballed by the watchdog group Action For Children's Television. They claimed that since it was bankrolled by game show producers Merrill Heatter and Bob Quigley ("Hollywood Squares"), it was enticing children to place monetary wagers on the outcome of each of the show's 34 races. (Hogwash. I had the over/under on how many times Dick Dastardly's contraptions backfired on him.)
For all the atypical Hanna-Barbera use of repeat animation and low-budget movement, "Wacky Races" was still an unusual and entertaining cartoon which would beget such shows as "Bailey's Comets," "Laff-A-Lympics" and "Yogi's Space Race." A lot of the humor derived from Dastardly's machinations, although many of the other racers got to shine as well. In the Gold Key comics, Penelope Pitstop would eliminate Peter Perfect and Red Max by conveniently getting them to fight over her. That wasn't used in the show, although it should have. And it's dotted with great lines. When the narrator calls Dastardly "The Dracula of the drag strip," Dastardly counters "I resent that remark!" Narrator: "But do you deny it?" Dastardly: "No, I just resent it!" It's a comedy cartoon that doesn't forget it's a comedy cartoon, something that many cartoon shows of the 70s and 80s forgot.
And a bit of trivia, Dastardly did cross the finish line twice but was disqualified both times. The first time he extended the nose of the Mean Machine ahead of the others (yet in another episode, Rufus Ruffcut physically extended his neck to reach the finish line and the judges gave him the win--go figure). The second time, a chain reaction collision caused Dastardly and Muttley to get bounced into the Arkansas Chuggabug, which was in the lead. Dastardly also set a precedent the following year--being the first (and to anyone's knowledge, only) villain to get his own show, "Dastardly & Muttley In Their Flying Machines.

冰雪融化，春暖花开。明媚的阳光下，杰力士森林公园里呈现出一派春天的景象。从冬眠中苏醒过来的小熊波波首先想到的，就是把自己的好朋友瑜伽叫醒。瑜伽可是一只了不起的宝贝。因为聪明、淘气，瑜伽不仅受到护林员让•斯密特的格外关照，就连州委员都知道瑜伽的大名。但除了聪明、淘气和老是惦记着弄点什么吃的，对于熊姑娘辛迪的爱，瑜伽好象有点不解风情。
正当瑜伽偷袭了森林里所有的野炊营地时，圣地亚哥动物园打来电话，想要几只小熊。护林员把这个“难得”的名额给了瑜伽，没想到灰熊“玉米饼”一听说可以去圣地亚哥，抢先一步上了开往圣地亚哥的车。拉着“玉米饼”的箱车一路绝尘而去，让包括波波和辛迪在内的每一个动物都觉得瑜伽离开了杰力士森林，去了遥远的圣地亚哥。
瑜伽“走了”。波波失去了最好的朋友，辛迪却不能忍受没有恋人的日子。在还没搞清楚森林管理处门前的箱车将开往何处时，辛迪就急不可耐地跳上车，等车到半路时，辛迪才搞明白最终的目的地不是圣地亚哥，而是圣路易斯。辛迪被颠下火车时，已经是繁星满天。就在辛迪举目无亲时，已经陷入经营困境的史泽林兄弟马戏团把辛迪拉做自己的杂技演员，主演踩钢丝。
没有波波和辛迪做伴的日子，再美丽的春天在瑜伽看来都索然无位。当瑜伽听波波说辛迪去圣地亚哥找自己后，拉着波波就朝圣地亚哥而来。一路阴差阳错的奇遇后，瑜伽和波波在一个小镇参加了动物们举行的游行活动。无意之中，路边的一张海报引起了波波的注意。天啊！辛迪就在小镇上，而且还是杂技明星。
找到杂技团，见到辛迪的那一刻，所有的误会都在激动的泪水中化为虚有。可是，贪心的格力夫特骗取了瑜伽的信任，在带瑜伽去见辛迪时，把瑜伽也关进了笼子，好在有波波相救，才得以逃出樊笼。当瑜伽带着辛迪和波波跳上一辆开往杰力士方向的车时，车子却在城市的中心停了下来。因为三只熊的出现，城市陷入混乱之中，直到政府和媒体把三只小熊的事搬上了电视，招来了让•护林员斯密特，瑜伽、辛迪、波波才重新回到了他们的乐园杰力斯公园。
