Laughing The Hoobs : Season 1 Episode 4

Nothing makes a Hoob laugh like a hoobledangler. And Tiddlypeeps laugh at all sorts of strange things but they don't don't find hoobledanglers funny at all. So what would make a Hoob AND a Tiddlypeep laugh? The Hoobs try to laugh at things in crackers, things you sit on and Peeps who fall over. But in the end it's something much simpler that's funny enough to make Groove drop his plank!
