The Wacky Adventures of Ronald McDonald facts for kids

Ronald and his friends go on a camping trip in the Far-Flung Forest, where Ronald discovers an old house which he assumes is haunted by a ghost called the Far-Flung Phantom. Due to a sudden storm, the campers are forced to stay in the old house, where a Phantom head leads them through a challenging game that will help them to escape, if they cooperate. Along the way, the Fry Kids and McNuggets get caught in traps and are separated from the group and the rest face off against the Phantom head in a challenge of riddles. Tika, Hamburglar, and Birdie fail each riddle and are swept into traps, leaving only Ronald, Grimace, and Sundae to solve the final one, which they do. The holographic head turns out to be a child named Franklin programming the game with help from Tika (who wanted to give Ronald a challenge) and the McNuggets in a lab room. After Ronald gets a "You Win" out of Franklin, Dr. Quizzical returns to catch his son in the act and reveals that Franklin has done something like this before. Franklin apologizes to the gang for his actions and is allowed to join in their camping trip, becoming their new friend in the process.

Note: The only appearance of the Fry Kids in the series.

Ronald and the gang go out on a journey to Grimace Island (where Grimace's species is originated) after Grimace receives a letter supposedly by the island's residents asking for help. Unbeknownst to everyone, the letter was actually written by pirate captain One-Eyed Sally and her first mate Blather in a scheme by the two to follow the gang to the island in order to seize the Grimaces' legendary treasure for themselves.

Note: Ronald and Sundae go down the ball pit slide. Tika was absent in this episode. The Fry Kids are absent in the video series

Hamburglar tricks the gang into believing that aliens have come to Earth so that he can steal McDonaldland's hamburgers without interference from them, which costs him their trust in him when they find out. Later, Hamburglar gets abducted by real aliens after foolishly accepting an offer to go on vacation with them, not realizing until too late that the vacation lasts thousands of Earth years. Despite being angry at him for his lie and prank, Ronald and his friends go on a mission in outer space to rescue Hamburglar.

Note: Ronald and Sundae go down the ball pit slide for the last time as this is the last episode to have the original introduction and closing. In this episode where Franklin and Tika was absent. It is also the last episode where Sundae appears in the live-action segments. Prior to this episode, there was a Rugrats episode with the same title.

Hamburglar is upset that he forgot Ronald's birthday and does not have a present for him until an evil mad scientist named Professor Thaddeus J. Pinchworm gives him tickets to a fake amusement park called Birthday World. During their visit, Ronald and his friends quickly become disappointed to find that most of the park's rides are broken and/or malfunctioning; they then ride a roller coaster which turns them into toddlers and babies with a ray. The gang then discovers that they were test subjects for Pinchworm's evil scheme to use a bigger version of the ray to de-age the world's population in order to achieve world domination. Despite the fact that the work has left their abilities limited, Ronald and his friends set out to stop Pinchworm's scheme and restore themselves to their regular ages.

Note: A new opening sequence was made for this episode and the next two. As a result, Sundae no longer appears in the live-action segments but is heard once offscreen.

While helping Franklin clean up his father's lab, Ronald and his pals stumble across a time machine in which Hamburglar dreams up a crazy scheme to use the time machine to get out of cleaning and they end up getting lost in time. Their time travel adventures take them to prehistoric times, where the time machine is nearly digested by a Tyrannosaurus and they meet their cavemen ancestors, medieval times, where they entertain the spoiled young King Murray with in order to save a captured Birdie, the Wild West, where they discover Hamburglar's ancestor Henry H. Burglar II (whom the residents mistake Hamburglar for) and the disco era of the 1970s, where they briefly encounter Mayor McCheese.

Note: The only episode where the McNuggets are absent.

The gang travels to a Scottish expedition known as Ol’ McDonaldland Loch where Sundae's cousin Scotty lives. They also come across a plot by a mad scientist named Stiles and his assistant Pip's attempt to build a replica of the Loch Ness Monster in order to make money from the discovery. Birdie befriends the real Loch Ness Monster, who is named Simon and wants his existence to be kept a secret. Despite not being good at keeping secrets, Birdie agrees to, but this becomes difficult when Stiles and Pip's scheme goes awry, putting everyone in danger.

Note: This episode was the rarest of all six, as it was only released online on the Klasky Csupo website on January 30, 2003 as opposed to McDonald's stores. The episode was titled "The Legend of Ol’ McDonaldland Loch" on most websites. It was also Christine Cavanaugh's final acting role, as it was released approximately two years after her retirement.
