The episode begins as Jenny, Brad, and Tuck arrive to Wizzly World! The happiest, most exciting place in town. Jenny is very excited to be there and she quickly finds a "kiddy ride" that she wishes to try out, "The World Ain't so Big". After the ride ends, both Brad and Tuck seem to have enjoyed the ride but Jenny is a little upset, going on to say that she feels badly for the many robots being prisoner and help captive there, stating that it's degrading.
Brad tries to tell her that it is their job, however, and it's just for the entertainment of the park's guests. Jenny then angrily pokes at Brad and Tuck, then states she isn't amused by the rides at this amusement park and the brothers run off to go and continue to enjoy the park. Jenny sees a group of kids harassing robots, a woman insulting a robotic hot dog vendor, and a man insulting an ice cream robot. She then exclaims that the robots need to unite and stop being the humans' slaves before proceeding to set every robot free from this amusement park.
As she then makes an announcement over the intercom, Brad and Tuck come to Jenny and tell her the robots shouldn't be left free and they're only happy due to programming, but she refuses to listen to them. The following morning, she wakes up surrounded by the many little people from the World Ain't so Big ride. They thank her for her help and explain that they like to be in this small bedroom, instead of outside where it's very big...
Suddenly hearing her mother shriek, Jenny pulls out one of the robots from the toilet and she tries to give him advice on how to do something with his life. Meanwhile outside, Brad and Tuck are being harassed by the food robots. She then notices all of the many robots causing problems around town when one suddenly explodes. Causing his head to fly away! Jenny then states that it couldn't get any worse, when suddenly a bell chimes from a clock tower, then and all of the robots begin to sing a very irritating song.
After they think it's over... the robots just sing it again causing everybody in town to leave the place, panicking and running away. Leading Jenny to relize that the robots do not belong here.
Later, Jenny returns all of her robot bretheren and sistren to the Amusement Park and Brad insists that they'll be happier there. She then suddenly gets an idea and loads every robot into a rocket, then throws it onto Mars that will allow them to build their own society.
On Mars, it has revealed that very tiny Martians live there, but they are annoyed by the robots singing as the episode ends...
Jenny: It's like the local fair, but with better rides and less dirt! Let's go on this ride!
Jenny: Robots of the park, unite! Throw off the shackles of oppression! Be slaves no more!
Jenny: You humans should be ashamed of yourselves! Be free little wood-land robots!
Racoon Robot: Where are we supposed to go?
Jenny: *darkly* I said: BE FREE!
Exit Robot: Have a nice day. Have a nice day. Have a nice day. Have a nice day.
Brad: OK, the waterfall was pretty weak. Just consider it a warm up for what's to come.
Jenny: A warm up?
Brad: Sure, ya gotta start somewhere.
Tuck And the rest of the rides only get better.
Jenny: (angrily) And do the rest of these rides make fools out of robots too?
Brad: What are you talking about?
Jenny: (imitating the motion) I'm talking about hydrolic surges forced into your hips to make them shake. Do you have any idea what that can do to a ball and socket joint?
Brad: Come on Jenny its all in good fun.
Jenny: Yeah, fun for the humans! How'd you like to sing some stupid song over and over all day long? (extends her fingers and begins poking Brad and Tuck after each sentence) Come on sing! Come on be happy! Come on! Come on! Come on! Come on! Come on! I'm not amused by the so-called rides and your so-called amusement park and i'm not going on any more of them.
Brad: Well I guess we can't force you to go on any more rides.
Tuck: We on the other hand are going on all of them in twice.
(Brad and Tuck we're running along laughing without Jenny. then Jenny stood here seeing the kids playing with robotic dog. then she sees a woman getting mad at robotic hot dog)
Woman: ONIONS AND NO KETCHUP YOU CALAMITOUS!!!
(Jenny rubs her tummy and getting a bit hungry off-screen then she sees a man holding ice cream, upsetting at robotic ice cream)
Man: Hey robot, pick that up, do you hear me pinhead? what you get a screw loose or something?
Jenny: Uh, excuse me! Pardon me! Excuse me! Excuse me! Sorry!
Mrs. Wakeman: (to Jenny) It's in the toilet.
Tuck: This is another fine mess you've gotten us into, Jennifer.
