Widget invents the Happy Hopper 3000 but it doesn't work, no matter how hard she tries to fix it. Widget gets the blooey blues, giving up on her machine and going to lie in bed. Wubbzy and Walden try to cheer her up by telling the best jokes, doing silly dances, and pretending to be clowns, but it doesn't work. Wubbzy and Walden decide to try and fix the Happy Hopper. Wubbzy realises that the Happy Hopper 3000 didn't work because the batteries fell out, but he puts them back in before making sure the machine was turned off. The Happy Hopper 3000 starts going and Wubbzy is stuck on top of it with no way to turn it off. Walden gets Widget out of bed by telling her that Wubbzy's in trouble, and together they save Wubbzy from the rampaging robot. This cures Widget's blooey blues.
