Knock Knock Joke: Pyxxi and Pyka

[xingcat]

Knock, knock! Who's there? Pyxxi is trying to tell Pyka a knock knock joke, but Pyka has never heard one before. While telling jokes is fun, it can be difficult when someone doesn't know how the joke goes. Still, trying to be funny and have a sense of humor is very fun for kids, so she keeps on trying! Will Pyka ever get it right?
