The original stand-up routine by
Robin Harris is shown in a brief live-action segment before an animated version of Harris woefully recounts his troubles to a blind bartender. He traces his problems back to Jamika, a woman he met at a funeral. Outside the wake, Robin approaches Jamika and asks her out. Jamika picks up her mild-mannered son, Leon, from the babysitter and invites Robin to come along with her to the amusement park, Fun World, which Robin agrees to. The next day, Jamika introduces Robin to the three children of her
hedonistic friend Bebe - consisting of LaShawn, Kahlil, and the smooth-talking baby Pee-Wee. All six travel to Fun World, but are confronted by security at the entrance, and warned they are being watched. Upon entering the park, Bebe's kids are set loose and promptly wreak havoc. Robin's disastrous outing is further disrupted by a chance encounter with his ex-wife, Dorothea, and her portly best friend, Vivian. After going on a couple of rides with Bebe's kids, Robin and Jamika let them go off on their own again as they attempt to enjoy a ride through the
Tunnel of Love, where Jamika commends Robin for his endurance. While Robin and Jamika spend time together on their own, Leon tries to fit in with Bebe's kids but is at first unsuccessful, although they allow him to tag along. The kids then resume their mischief until they are caught by security. However, they escape and convince a group of other free-range children to spread the chaos. Meanwhile, Dorothea and Vivian attempt to sabotage the growing relationship between Robin and Jamika but are thwarted by Robin. Elsewhere, in an abandoned building, Leon and Bebe's kids finds
animatronic versions of the
Terminator,
Abraham Lincoln and
Richard Nixon, and are put on trial. The Terminator animatronic acts as judge who decides whether their antics are worth sending to the electric chair, while Lincoln acts as the Bebe's kids' defense attorney with "Nixon" as the prosecutor. Leon proves his courage through a rap that not only wins their freedom but also gains him Bebe's kids' respect. They celebrate their victory by stealing a pirate ship and crashing it into a recreation of the
RMS Titanic, taking the crew and passengers hostage, including Dorothea and Vivian. Robin and Jamika finally leave Fun World, with the park ultimately crumbling in destruction through Robin's rearview mirror. When a cop passes, Robin tries to get his attention, but Bebe's kids scare the officer away. Robin drops Bebe's kids off at their apartment, where he sees how they really live. Bebe, as usual, is nowhere to be seen, and has left a note on the empty refrigerator, expecting Jamika to feed the kids. Sad to see Robin go, Bebe's kids bid him an emotional goodbye, but not before he gives them what money he has left so they can order themselves a pizza. At the bar, Robin has a change of heart and returns to hang out with Bebe's kids a little while longer, despite all the mayhem they've caused. The kids force him to take them all to
Las Vegas, where everybody flees in terror when they recognize the kids. Pee-Wee finds and pulls a plug out of a socket, causing a citywide
blackout. ==Voice cast==
